If a linear search is performed on an array, and it is known that some items are searched for more frequently than others, how can the contents of the array be reordered to improve the average performance of the search?
The element being searched for is not in an array of 100 elements. What is the maximum number of comparisons needed in a sequential search to determine that the element is not there if the elements are completely unsorted?
Given an 8-element array: A = {x1, X2, X3, X4, X5, X6, 7, x8}, we would like to find
its 3rd smallest element. It is known that x₁ and 8 are the two extreme elements:
max and min, but we do not know which one is the max and which one is the min.
It is also known that x4 and x5 are the two medians: left-median and right-median.
What is the minimum number of comparisons you need to find the 3rd smallest
element of the original array?

- When we apply the mergesort on a 12-element array, how many comparisons do we need for the worst case? Ans:arrow_forwardFor insertion sort, how many comparisons would be needed to sort an array containing 100 elements if the original array elements were already sorted? What if the original array elements were sorted in reverse order? AV What if the original array elements were all identical?arrow_forwardUse the 5 by 4 array with a first row of [1.,2.,3.,4], second row of [5.,6.,7.,8.], etc from the last question. Call it A. Transpose A (so that the rows become the columns and the columns the rows) and call the result B. Then compute A times B and B times A using matrix multiplication.arrow_forward
