An integer x is numerically balanced if for every digit d in the number x, there are exactly d occurrences of that digit in x.

\n\n

Given an integer n, return the smallest numerically balanced number strictly greater than n.

\n\n

 

\n

Example 1:

\n\n
\nInput: n = 1\nOutput: 22\nExplanation: \n22 is numerically balanced since:\n- The digit 2 occurs 2 times. \nIt is also the smallest numerically balanced number strictly greater than 1.\n
\n\n

Example 2:

\n\n
\nInput: n = 1000\nOutput: 1333\nExplanation: \n1333 is numerically balanced since:\n- The digit 1 occurs 1 time.\n- The digit 3 occurs 3 times. \nIt is also the smallest numerically balanced number strictly greater than 1000.\nNote that 1022 cannot be the answer because 0 appeared more than 0 times.\n
\n\n

Example 3:

\n\n
\nInput: n = 3000\nOutput: 3133\nExplanation: \n3133 is numerically balanced since:\n- The digit 1 occurs 1 time.\n- The digit 3 occurs 3 times.\nIt is also the smallest numerically balanced number strictly greater than 3000.\n
