You are given two positive integers n and target.
An integer is considered beautiful if the sum of its digits is less than or equal to target.
Return the minimum non-negative integer x such that n + x is beautiful. The input will be generated such that it is always possible to make n beautiful.
\n
Example 1:
\n\n\nInput: n = 16, target = 6\nOutput: 4\nExplanation: Initially n is 16 and its digit sum is 1 + 6 = 7. After adding 4, n becomes 20 and digit sum becomes 2 + 0 = 2. It can be shown that we can not make n beautiful with adding non-negative integer less than 4.\n\n\n
Example 2:
\n\n\nInput: n = 467, target = 6\nOutput: 33\nExplanation: Initially n is 467 and its digit sum is 4 + 6 + 7 = 17. After adding 33, n becomes 500 and digit sum becomes 5 + 0 + 0 = 5. It can be shown that we can not make n beautiful with adding non-negative integer less than 33.\n\n\n
Example 3:
\n\n\nInput: n = 1, target = 1\nOutput: 0\nExplanation: Initially n is 1 and its digit sum is 1, which is already smaller than or equal to target.\n\n\n
