Given a string containing alphanumeric characters how could you write a function to output a repeated characters if any number is present before the character in a string? Input: as2d3c[x]4b Output: asddcccxbbbb

Question

Accepted Answer

The function should output repeated characters based on the numbers present before each character in the input string.

Iterate through the input string character by character.
If a number is encountered, store it as the repeat count for the next character.
If a character is encountered, repeat it based on the stored count and append to the output string.
Handle special characters like brackets separately.
Example: Input 'as2d3c[x]4b' should output 'asddcccxbbbb'.
