Given an array of integers, find out minimum and maximum element present using minimum comparisons.

Given an array, find peak element in it. A peak element is an element that is greater than its neighbors.

Given a sorted binary array, efficiently find the number of 1’s in it.

Given a nearly sorted array such that each of the N elements may be misplaced by no more than one position from the correct sorted order, efficiently search a given element in it. Report if the element is not present in the input array. An element at index i in correct sorted order can …

Given a sorted array of integers, find floor and ceil of a given number in it. The floor and ceiling map the given number to the largest previous or the smallest following integer, respectively. More precisely, for a number x, floor(x) is the largest integer less than or equal to x and ceiling(x) is the …
