Give me a code to ways of transforming one string to other by removing 0 or more characters and the other steps required given the following:
Ways of transforming one string to other by removing 0 or more characters | Python3 program to count the distinct transformation of one string to other ..
If b = " " i . e . , an empty string . There is only one way to transform ( remove all characters ).
Fill dp [ ] [ ] in bottom up manner Traverse all character of b [ ].
Traverse all characters of a [ ] for b [ i ].
Filling the first row of the dp matrix ..
Filling other rows.
