- Let N be an unordered array of integers. The maximum number of compares required to find the minimum value is N. Select one True or FalseTo compute the average of the squares of the elements of a vector V, aka the mean square, we (Note: use randn to create a random vector) Select one: a. We use polyfit which does least squares and skip the minimization part b.we use sum(V.^2)./length(V*V) c.we use sum(V.*V)/length(V) d.we use mean(V) e.we use sum(V^2)/length(V)Write the state of the elements of the vector below after each of the first 4 passes of the outermost loop of the insertion sort algorithm. (After the first pass, 2 elements should be sorted. After the second pass, 3 elements should be sorted. And so on.) // index 0 1 2 3 4 5 6 7 vector<int> numbers{29, 17, 3, 94, 46, 8, -4, 12}; insertionSort(numbers); NOTE: Write your answer inside curly braces with numbers separated by commas {29, 17, 3, 94, 46, 8, -4, 12} after pass 1 after pass 2 after pass 3 after pass 4
- - In class HashTable implement a hash table and consider the following:(i) Keys are integers (therefore also negative!) and should be stored in the tableint[] data.(ii) As a hash function take h(x) = (x · 701) mod 2000. The size of the table istherefore 2000. Be careful when computing the index of a negative key. Forexample, the index of the key x = −10 ish(−10) = (−7010) mod 2000 = (2000(−4) + 990) mod 2000 = 990.Hence, indices should be non-negative integers between 0 and 1999!(iii) Implement insert, which takes an integer and inserts it into a table. Themethod returns true, if the insertion is successful. If an element is already inthe table, the function insert should return false.(iv) Implement search, which takes an integer and finds it in the table. The methodreturns true, if the search is successful and false otherwise.(v) Implement delete, which takes an integer and deletes it form the table. Themethod returns true, if the deletion is successful and false otherwise.(vi)…6. Which of the following code snippet performs linear search recursively?The contents of the array below represent a BST (Binary Search Tree). What would be the contents of the array after 30 is deleted. Briefly explain how 30 would be deleted. Use an X to represent any empty spots in the array. 30 2050 10 25 40 60
- Suppose we are performing a binary search on a sorted vector initialized as follows: // index 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16vector<int>numbers { 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24, 26, 28, 30, 32, 34};intindex=binarySearch(numbers, 28); Write the indexes of the elements that would be examined by the binary search (the mid values in our algorithm's code) and write the value that would be returned from the search. find: indexes examined value returnedThe algorithm: –In an array of n elements, go to index [n/2] –If the record there is the one you want, you are done –If the record value there is smaller than your search value, all records less than the current record can be ignored – set your search range of elements to [n/2+1…n] and return to step 1 –Otherwise, set your range of elements to [0…(n/2)-1] and return to step 1 –Repeat this loop until you have 0 elements (record is not found) or record is found Short answer Another approach to the update algorithm is to perform use the delete function for the old value and if it is successful, call the insert function using the new value. Explain in your own words if you think this approach is significantly better, worse, or in the same category as the algorithm discussed in the slides, and why.Description: Given a string, find the first non-repeating character in it and return its index. If it doesn't exist, return -1. Example 1 input: "leetcode" output: 0 Example 2 input: "loveleetcode" output: 2 The solution we are targeting here is a linear time solution since we have to go over the entire string to know which one is unique in it. A straightforward method we can easily think of is having a Dictionary record letter frequency. Subsequently, iterate over the input again and return the index that has a letter frequency of 1.
