/*
Given an array ar[N] , you have to find a number of leaders in the arry . 
Leader : An elemet ar[i] is said to be a leader if it is greater than the maximum of all elements present on the left of it i.e. [0,i-1]

Note : ar[0] is already considered a leader

Constraints : 1 <= N <= 10^5
              1 <= ar[i] <= 10^9
