Question

1. Suppose we use RANDOMIZED-SELECT to select the minimum element
of the array A = {12, 0, 4, 3, 5, 7, 9, 2, 8, 11}. Describe a sequence of
partitions that results in a worst-case performance of RANDOMIZEDSELECT.

2. Illustrate the operation of COUNTING-SORT on the array A = {6, 0, 2, 0, 1, 3, 5, 6, 1, 3,2}. Specifically, show the four arrays A, B, C, and C’.

Consider this alogrithm:// pre: array A of length n, each A[i] is picked randomly uniformly// from the set {0,1,2,3,4,5,6,7,8,9}.// post: return the index of the first occurrence of "check digit" of A// (already computed in the code)// return -1 if check digit is not foundint FindCheckDigit(A) {check_digit = 0for (i=0; i < n; i++) check_digit = check_digit + A[i]check_digit = check_digit % 10 # % means remainder of divisionfor (i = 0; i < n; i++) { if (A[i] == check_digit) { return i }}return -1;}Compute the average runtime for this algorithm. Show all details of your computation for both loops.
.Here an array of integers nums sorted in ascending order, find the startingand ending position of a given target value. If the target is not found in thearray, return [-1, -1]. For example:Input: nums = [5,7,7,8,8,8,10], target = 8Output: [3,5]Input: nums = [5,7,7,8,8,8,10], target = 11Output: [-1,-1].
The algorithm below searches for the maximum in an input array A. Assume A is a random sequence containing n distinguishable real numbers, what is the probability for line #4 to be executed exactly once? (The phrase "random sequence" here means the n numbers can appear in any order with equal chance.) mymax(A, n) { 1: max = A[1]; 2: for i = 2:n 3: if A[i] > max 4: max = A[i); 5: end; 6: end; 7: return max; }
Can someone help me with this algorithm? No coding needed
You are given two arrays, one shorter (with all separate items) and one longer (with no unique elements). Find the shortest subarray in the larger array that contains all of the shorter array's items. The things can be shown in any order.EXAMPLEInput: {1, 5, 9}{7, 5, 9, 0, 2, 1, 3, 5. 7, 9. 1, 1, 5, 8, 8, 9, 7}Results: [7, 10] (the underlined portion above)
Let A be an array, where each of the n elements is a randomly chosen digit between 0 and 9. For example, if n = 12, this array could be A = [3,5,1,0,5,7,9,2,2,8,8,6]. Determine whether Counting Sort or Merge Sort sorts this array faster.

Let M(n) be the minimum number of comparisons needed to sort an array A with exactly n ele- ments. For example, M(1) = 0, M(2) = 1, and M(4) = 4. If n is an even number, clearly explain why M(n) = 2M(n/2) + n/2.
