Count Subsequences Problem Statement
Given an integer array ARR of size N, your task is to find the total number of subsequences in which all elements are equal.
Explanation:
A subsequence of an array i...read more
Ans. Brute Force
The idea is to generate all the subsequences and check whether the elements present are equal or not.
 
Here is the algorithm :
 
1. Generate all the subsequences of the given array.
2. Maintain a variable ‘COUNT’ which stores the total number of subsequences in which all the elements are equal.

While coming back from each recursion call we add the current node in the current recursion call to the last node of the partially reversed Linked List and assign the current node to null.
