Lexicographically smallest string after M operations | Function to find the lexicographical smallest string after performing M operations.
Size of the given string.
Declare an array a.
For each i , a [ i ] contain number of operations to update s [ i ] to 'a.
Check if m >= ar [ i ] , then update s [ i ] to ' a ' decrement k by a [ i ].
Form a cycle of 26.
Return the answer.

How can the above be solved in Python?

Can you provide a code to lexicographically smallest string after M operations and the other steps required?
