Transform a string such that it has abcd . . z as a subsequence | function to transform string with string passed as reference.
initializing the variable ch to 'a.
if the length of string is less than 26 , we can 't obtain the required  subsequence.
if ch has reached ' z ' , it means we have transformed our string such that required subsequence can be obtained.
current character is not greater than ch , then replace it with ch and increment ch.
Driver Code"
How can the above be solved in Python?
 Can you provide a code to transform a string such that it has abcd?
