Array creation: There are various ways to create arrays in NumPy. O For example, you can create an array from a regular Python list or tuple using the array function. The type of the resulting array is deduced from the type of the elements in the sequences. O Often, the elements of an array are originally unknown, but its size is known. Hence, NumPy offers several functions to create arrays with initial placeholder content. These minimize the necessity of growing arrays, an expensive operation. For example: np.zeros, np.ones, np.full, np.empty, etc. O To create sequences of numbers, NumPy provides a function analogous to, range that returns arrays instead of lists. O arange: returns evenly spaced values within a given interval. step size is specified. O linspace: returns evenly spaced values within a given interval. num no. of elements are returned. O Reshaping array: We can use reshape method to reshape an array. Consider an array with shape (a1, a2, a3, ., aN). We can reshape and convert it into another array with shape (b1, b2, b3, ., bM). The only required condition is: al x a2 x a3 . x aN = b1 x b2 x b3 ... x bM. (i.e original size of array romainc unchannad i

Rotate Right k cells (use python) Consider an array named source. Write a method/function named rotateRight( source, k) that rotates all the elements of the source array to the right by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] rotateRight(source,3) After calling rotateRight(source,3), printing the array should give the output as: [ 40, 50, 60, 10, 20, 30]
Shift Right k Cells (Use Python) Consider an array named source. Write a method/function named shifRight( source, k) that shifts all the elements of the source array to the right by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] shiftRight(source,3) After calling shiftRight(source,3), printing the array should give the output as: [ 0,0,0,10,20,30 ]

1. Shift Left k Cells Use Python Consider an array named source. Write a method/function named shiftLeft( source, k) that shifts all the elements of the source array to the left by 'k' positions. You must execute the method by passing an array and number of cells to be shifted. After calling the method, print the array to show whether the elements have been shifted properly. Example: source=[10,20,30,40,50,60] shiftLeft(source,3) After calling shiftLeft(source,3), printing the array should give the output as: [ 40, 50, 60, 0, 0, 0 ]
8. Repetition Use Python Language Write a method that takes in an array as a parameter and counts the repetition of each element. That is, if an element has appeared in the array more than once, then its 'repetition' is its number of occurrences. The method returns true if there are at least two elements with the same number of 'repetition'. Otherwise, return false. Input: {4,5,6,6,4,3,6,4} Output: True Explanation: Two numbers repeat in this array: 4 and 6. 4 has a repetition of 3, 6 has a repetition of 3. Since two numbers have the same repetition output is True. Input: {3,4,6,3,4,7,4,6,8,6,6} Output: False Explanation: Three numbers repeat in this array:3,4 and 6 .3 has a repetition of 2, 4 has a repetition of 3, 6 has a repetition of 4. Since no two numbers have the same repetition output is False.
Arrays: create an array of a given type and populate its values. Use of for loop to traverse through an array to do the following : to print the elements one by one, to search the array for a given value. ArrayList: create an ArrayList containing elements of a given type . Use some of the common ArrayList methods to manipulate contents of the ArrayList. Write methods that will take an ArrayList as its parameter/argument ; and/or return an ArrayList reference variable as its return type. Searching for an object in an Array: Loop through the ArrayList to extract each object and to check if this object’s attribute has a given value. Explain how and why interfaces are used in Java Collection Framework. Explain the major differences between a Stack and a Queue. Be able to use stack and queue methods.

DNA Max Write code to find which of the strands representing DNA in an array String[] strands representing strands of DNA has the most occurrences of the nucleotide represented by parameter nuc. Complete the definition of the class DnaMax and method definition maxStrand shown below. If more than one strand has the same maximal number of the specified nucleotide you should return the longest strand with the maximal number. All DNA strands have different lengths in this problem so the maximal strand will be unique when length is accounted for. Return this uniquely maximal strand. Each String representing a DNA strand will contain only cytosine, guanine, thymine, and adenine, represented by the characters 'c', 'g', 't', and 'a', respectively. If no strand in the array contains the specified nucleotide return the empty string "". public class DnaMax { public String maxStrand(String[] strands, String nuc) { // fill in code here } } Constraints strands will contain no more than 50 elements,…
Best 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…
Circular Array 1. Palindrome Use python Write a method/function that takes in a circular array, its size and start index and finds whether the elements in the array form a palindrome or not. Return true if the elements form a palindrome, otherwise, return false. Example: Input: [20,10,0,0,0,10,20,30] (start =5, size=5) Output: True. Input:[10,20,0,0,0,10,20,30] (start =5, size=5) Output: False

10 Build the Sudoku Reviewer ( the testing program). The specification is below. Please note: you DO NOT have to build a Sudoku solver. To test you just need to build a class that generates a 9x9 2D array with the values you want to test. You can assume the value types are valid. (integers from 1-9). 1-The main purpose is to make sure the Sudoku solver actually solved it correctly! 2- You are also confirming the solver solves puzzle in no longer than a minute 3- Solver (not the reviewer) requires 7 INDICES (ELEMENTS) filled in the input array at least. 4- The reviewer receives both the original puzzle and the solution. The Reviewer needs to confirm the solution is not only a valid SudoKu solution but also the solution to the original puzzle. 5- Solver will return a 2d array filled with -1s if input array has an error/bad input (exception). Reviewer will check for this case.
