Problem Link - Leader of an Array in Arrays

Problem Statement:

Given an array A of length N. We have to print all the leaders in the array. An element is a leader if it is strictly greater than all the elements to its right side. And the rightmost element is always a leader.

Approach:

  • For each element A[i] in the array:
    • The inner loop checks if there is any element to the right of A[i] that is greater than or equal to A[i]. If such an element exists, the loop breaks.
    • If no element to the right is greater than or equal to A[i], it means A[i] is a leader.

Complexity:

  • Time Complexity: O(N^2) using two nested loops
  • Space Complexity: O(1) No extra space is used to store the result.
