Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response. Can you imagine our life if we removed all zeros from it? For sure we will have many problems. In this problem we will have a simple example if we removed all zeros from our life, it's the addition operation. Let's assume you are given this equation a + b = c, where a and b are positive integers, and c is the sum of a and b. Now let's remove all zeros from this equation. Will the equation remain correct after removing all zeros? For example if the equation is 101 + 102 = 203, if we removed all zeros it will be 11 + 12 = 23 which is still a correct equation. But if the equation is 105 + 106 = 211, if we removed all zeros it will be 15 + 16 = 211 which is not a correct equation. Input The input will consist of two lines, the first line will contain the integer a, and the second line will contain the integer b which are in the equation as described above (1 ≤ a, b ≤ 109). There won't be any leading zeros in both. The value of c should be calculated as c = a + b. Output The output will be just one line, you should print "YES" if the equation will remain correct after removing all zeros, and print "NO" otherwise. Examples Input 101 102 Output YES Input 105 106 Output NO Submitted Solution: ``` a0 = int(input()) b0 = int(input()) s0 = a0 + b0 numbers = [a0, b0, s0] i = 0 while i < 3: num = numbers[i] new_num, rank = 0, 0 while num > 0: last = num % 10 if last != 0: new_num += last * 10 ** rank rank += 1 num //= 10 i += 1 numbers.append(new_num) if numbers[3] + numbers[4] == numbers[5]: print('YES') else: print('NO') ```

Provide a correct Python 3 solution for this coding contest problem. There are N integers written on a blackboard. The i-th integer is A_i. Takahashi will repeatedly perform the following operation on these numbers: * Select a pair of integers, A_i and A_j, that have the same parity (that is, both are even or both are odd) and erase them. * Then, write a new integer on the blackboard that is equal to the sum of those integers, A_i+A_j.
