DCEPC810 - Cousin Wars
Sunny is fond of words. He got a new game to play with his cousin Sonali.He gives her a long string and two other smaller strings(A and B).Now he asks Sonali to find the number of all the subsequences of the long string that are greater than equal to smaller string A and less than equal to smaller string B.
Help Sonali to find the answer.
Note : Comparison of two strings is regarded same as that done by the string:compare function.
Empty string is not regarded as a subsequence.
Each input consists of 3 lines.First line has the TEXT string.
2nd and 3rd line contain two smaller strings A and B .
One number which gives the count such that
A <= subsequence of (TEXT) <= B
Input will consist of all lowercase characters.
1 <= Length of TEXT <= 25
1<= Length of A and B <= Length of TEXT
fc Output: 24
also check if A > B. in that case print 0.Last edit: 2022-03-02 19:08:35
I felt if was a pretty easy problem. Not trivial by any means, but there should really be more AC submissions. Get to work people! :)
How could the answer ever be negative? If A>B (string::compare again) the result is simply 0.

Don't print negative answers...make it 0
