Interview

Problem : Given an array of integers, you need to segregate odd and even numbers in an array. Please note : Order of elements can be changed. For example: arr[] = {12, 17, 70, 15, 22, 65, 21, 90} Array after separating odd and even numbers : {12, 90, 70, 22, 15, 65, 21, 17} […]

Problem: We need to print all the leaders present in the array. Element is the leader if it is greater than right side of elements. For example: arr[]={14, 12, 70, 15, 99, 65, 21, 90} Here 99 and 90 are leader elements Solution: Solution 1: Use two loops. Outer loop to iterate over array elements […]
