Check whether a + b = c or not after removing all zeroes from a,b and c

Given two integers a and b, the task is to add them to get c. After that remove zeroes from a, b and c and check for modified values if a + b = c then return “YES” else return “NO”.

Input: a = 101, b = 102
Output: YES
101 + 102 = 203.
After removing all zeroes from a, b and c, a = 11, b = 12 and c = 23
Now check if a + b = c i.e. 11 + 12 = 23 . So print Yes.

Input: a = 105, b = 108
Output: NO
After removing all zeroes a + b!= c, therefore the output is NO.
