Mergesort is also a divide and conquer algorithm. It continuously divides an array into two halves, recurses on both the left subarray and right subarray and then merges the two sorted halves Stable: Yes Time Complexity: Best Case: O(nlog(n)) Worst Case: O(nlog(n)) Average Case: O(...
O(n2) time complexity and O(1) space complexity squareSum.cpp Given an unsorted array arr[0..n-1] of size n, find the minimum length subarray arr[s..e] such that sorting this subarray makes the whole array sorted. minLengthUnsortedArray.cpp Find the missing number in Arithmetic ...
Given an array of positive integers, truncate it such that2×minbecomes more thanmax, and the total number of removals is minimal. Theminandmaxare the minimum and the maximum elements in the array, respectively. The elements can be removed either from the start or end of the array if the...
