Lexicographically smallest string possible by performing K operations on a given string | Function to find the lexicographically smallest possible string by performing K operations on string S.
Store the size of string , s.
Check if k >= n , if true , convert every character to 'a.
Iterate in range [ 0 , n - 1 ] using i.
When k reaches 0 , break the loop.
If current character is ' a ' , continue.
Otherwise , iterate in the range [ i + 1 , n - 1 ] using j.
Check if s [ j ] > s [ i ].
If true , set s [ j ] = s [ i ] and break out of the loop.
Check if j reaches the last index.
Update S [ i ].
Decrement k by 1.
Print string.
Driver Code.
Given String , s.
Given k.
Function Call"
How can the above be solved in Python?
