Assume nums is an array of integers that looks like this: If we are sorting from smallest to largest, what will nums look like after 2 times through the outside loop if we are using bubble sort? Note: When you're entering the values, make sure you leave at least one space between them. Would it be possible to perform a linear search on a 2-D array? Answers: Yes, but you would be limited to using only one loop No, because a 2-D array is not stored in linear fashion in RAM Yes, as long as you used the proper nested loops No, you would have to use a binary search Yes, but only if the array's elements were sorted

- Question 8 Sort the following numbers using an "in place" version of a selection sort. This means that you should have only one array throughout and all elements should be present at all times. Show each "pass" of the algorithm. 34, 25, 11, 44, 21, 8, 4, 28, 16, 31Java Program Your program should use 2D arrays to implement simple matrix operations. Your program should do the following: • Read the number of rows and columns of a matrix M1 from the user. Use an input validation loop to make sure the values are greater than 0. • Read the elements of M1 in row major order • Print M1 to the console; make sure you format as a matirx • Repeat the previous steps for a second matrix M2 • Create a matrix M3 that is the transpose of M1 and print it to the console • Check if M1 and M2 can be added (should have the same dimensions). If possible, add M1 and M2 and print the result to the console. Otherwise print an error message. • Extra credit: Multiply M1 and M2 if possible and print to the console. If the matrices cannot be multiplied, print an error message. Implementation requirements: • Use a helper method for reading a positive integer using an input validation loop. • Use a helper method for printing a matrix. Your helper methods should be private and…Create a 1D integer array of size 17. Fill each index with a random value ranging from 1 to 359 inclusive. You will then design and implement the Random Sort algorithm using the following methods: Create a method called check_if_sorted (). It should take in a 1D integer array and return a boolean value. It should return TRUE if the array is sorted in nondescending order, and FALSE otherwise. Hint: If you compare elements in the array and a pair is in the wrong order, that would mean the array is not in non-descending order. Create a method called shuffleArray (). It should take in a 1D integer array and return a 1D integer array. Shuffle the array so that the values are in random different indexes, and return altered array. Hint: There are many approaches to solve this problem – making a second array in the shuffleArray () method might be part of the answer. Create a method called PrintArray (). It should take in a 1D integer array and return nothing. Simply print the current values…
- Select true or false for the statements below. Explain your answers if you like to receive partial credit Select true or false for the statements below. Explain your answers if you like to receive partial credit Which of the following is true about searching elements in an unordered array? With the data is unsorted, search is O(n) because if the element you are looking for is not there, you have to check every element in the array If you start at the end of the array and traverse to index 0, search improves to O(log n) because you only have to look at half of the array If you get lucky with checking the first element and find it immediately, then the worst case performance of search improves to O(n^2) Which of the following is true about searching elements in an ordered array? You cannot use binary search on an ordered array so the performance is O(n) If there are no holes in the array and the elements are all next to each other, then the performance for search improves to…Homework 7: Merging two sorted arrays Due date: Saturday March 18. Objectives: Learn to implement algorithms that work with multiple arrays. Understand the Merging algorithm. IMPORTANT. Carefully study Lecture 1 from Week 8 on D2L before you start on this. Sometimes we need to combine the values in two sorted sequences to produce a larger sorted sequence. This process is called Merging. As an example, if the first sequence (S1)contains the numbers 2 3 4 4 5 9 and the second sequence (S2) contains the numbers 1 4 5 8 9 11 12 13 17 the output sequence will contain 1 2 3 4 4 4 5 5 8 9 9 11 12 13 17 Each sequence can be stored in an array. The strategy is as follows: Start by comparing the first items in the two input arrays. Write the smaller number to the output array, and move to the the next item in that array. This is repeated until we reach the end of any one of the input arrays; thereafter, we simply copy all the numbers from the other input array to the output array. (In the…True or False For each statement below, indicate whether you think it is True or False. Inserting elements into a sorted array is O(n) because you have to find the location to add the new element and then shift the remaining elements If the sorted array gets too large, the performance of binary search becomes O(n) For the delete algorithm, after you find the element to delete, you can make the algorithm run faster by replacing it with the last element in the array If you used binary search to find the element to delete, the performance is still O(n) because you may have to shift all elements
- Suppose an array has n elements. This _____ sorts to sort and array works as follows: Find the smallest element and place it in the first position. Then find the smallest of the remaining n-1 elements and place it in the second position. Repeat on n-2 elements, n-3 elements, ..., until the array is sorted.Python Write a Python program that performs a linear (sequential) search. Define an array of 10 non-sequential numbers. Ask the user for a number, such as "Enter a number to be found:" Search the array for the user's number. If present, display "Successful search, the element is found at position " and its position. Otherwise, display "Number not found."Given an array of 5-DWORD elements with values: 10,3,9,8,2 copy the values from last to first to a second 5-DWORD-element array Note 1: Use the loop as well as push and pop instructions Note 2: Use the LENGTHOF operator to get the number of elements of the array Note 3: Your algorithm should work for any array irrespective of its size with minimal mod- ifications
- Given the following 1D array of 7 strings: "MILK" "TEETH" The first element located at index 0 is "MILK". The last element located at index 6 is "APPLE". (Note that the indexing starts from 0) "HORSE" "YOYO" 1. Right after the first iteration, the element at index 6 is: Fill in the blanks below: 2. Right after the second iteration, the element at index 1 is: Perform Selection Sort to rearrange the elements in alphabetical order. Simulate the algorithm and fill in the required array element values in the following items. You have the option not to to type the double quotes in your answers. Use ALL CAPS when entering the text. 3. Right after the third iteration, the element at index 6 is: "ROBOT" 4. Right after the fourth iteration, the element at index 3 is: "QUEEN" "APPLE" MILKBest Partition You are given an array of positive numbers of size N and an integer K. You need to partition the array into K continuous segments. For each segment, the sum of its elements needs to be calculated. The segment with the minimum sum is called the bestSegment and the sum of the elements of the bestSegment is called the bestSum. For all possible combinations of partitions of the array when divided into K segments, their bestSum needs to be calculated and the one among them with maximum value needs to be returned. Input Specification: input1: an array of N positive numbers input2: an integer N denoting the length of the array input3: an integer K Output Specification: Return an integer denoting the maximum value of all possible bestSum. Example 1: input1: (1,2,3,4} input2: 4 input3: 2 Output: 4 Explanation: You can partition the given array into 2 continuous segments in the following manner- • 123 14- the sum of individual segments is (6,4) and the bestSum is 4 • 12134- the…The binary search algorithm that follows may be used to search an array when the elements are in order. This algorithm is analogous to the following approach to finding a name in a telephone book. a. Open the book in the middle and look at the middle name on the page. b. b. If the middle name isn't the one, you're looking for, decide whether it comes before or after the name you want. c. Take the appropriate half of the section of the book you were looking in and repeat these steps until you land on the name. 1. Let the bottom be the subscript of the initial array element. 2. Let the top be the subscript of the last array element. 3. Let found be false. 4. Repeat as long as the bottom isn't greater than the top and the target has not been found. 5. Let middle be the subscript of the element halfway between bottom and top. 6. If the element in the middle is the target 7. Set found to true and index to middle. else if the element in the middle is larger than the target 8. Let the top be…
