Dynamic programming – Minimum Jumps to reach to end

Objective:  Given an array of non negative integers, start from the first element and reach the last by jumping. The jump length can be at most the value at the current position in the array....


Find two non-repeating numbers in an array in O(n) time and O(1) space

Objective:  Given an array of integers which has all the repeating numbers (twice) but two numbers which are non-repeating. Write an algorithm to find out those two numbers. Example int [] arrA = {4,5,4,5,3,2,9,3,9,8}; Output:...


Majority Element- Boyer–Moore majority vote algorithm

Objec­tive:  Given an array of integer write an algorithm to find the majority element in it (if exist). Majority Element: If an element appears more than n/2 times in array where n is the size...
