True False Given a sorted array of n integers, we can find the median of them in O(1) time. True False If f = 0(g), then g = 0(f). True False

One disadvantage of using a For-loop in sorting algorithms is that the body of theFor-loop is repeatedly executed even if it is no longer necessary. One example isBubble Sort:Input: Array A[1 . . . n]Output: Array A sortedfor i ←1 to (n −1) dofor j ←1 to (n −i) doif A[j] > A[j + 1] thenA[j] ↔A[j + 1]return AIn the array [2, 1, 3, 7, 9] we know that when 2 and 1 are interchanged, early on in theexecution of the algorithm, the array is now sorted, and all subsequent iterations ofthe outer loop are unnecessary.  *Write a version of Bubble Sort that avoids unnecessary comparisons*

Given a set of numbers: A = {3, 41, 52, 26, 38, 57, 9, 49}. Use binary-search for finding the number 38 for the sorted array based on Question 1, show each step. No Code neded please

To binary search for a key in a sorted array, the maximum number of comparisons is log2 n. Choose one: Is it true or false?
