# Largest Number Possible After At Most K Swaps

easy

1. You are given a string which represents digits of a number. 2. You have to create the maximum number by performing at-most k swap operations on its digits. Note -> Check out the question video and write the recursive code as it is intended without changing signature. The judge can't force you but intends you to teach a concept.

## Constraints

1 <= length of S <= 30 1 <= K <= 10

## Format

### Input

A string S and a number K

A number

## Example

Sample Input

```.css-23h8hz{color:inherit;font-size:0.875rem;line-height:1.125rem;letter-spacing:0.016rem;font-weight:var(--chakra-fontWeights-normal);white-space:pre-wrap;}1234567 4```

### Sample Output

`.css-3oaykw{color:var(--chakra-colors-active-primary);font-size:0.875rem;line-height:1.125rem;letter-spacing:0.016rem;font-weight:var(--chakra-fontWeights-normal);white-space:pre-wrap;font-family:Monospace;}7654321`
