# Check if the sum of distinct digits of two integers are equal

Given two integer m and n, the task is to find the sum of distinct digits of both the numbers and print YES if the both the sums are equal else print NO.

Examples:

Input: m = 2452, n = 9222
Output: YES
The sum of distinct digits of 2452 is 11 (2 + 4 + 5)
And of 9222 is 11 (9 + 2)

Input: m = 121, n = 3035
Output: NO

## Recommended: Please try your approach on {IDE} first, before moving on to the solution.

Approach: Find the sum of unique digits of m and n and store them in sumM and sumN respectively. If sumM = sumN then print YES else print NO.

Below is the implementation of the above approach:
