Smallest window in a string containing all the characters of another string
This video is part of Strings section under GFG SDE Sheet.
In this video, we are given, two strings S and P. Find the smallest window in the string S consisting of all the characters(including duplicates) of the string P. Return "-1" in case there is no such window present. In case there are multiple such windows of same length, return the one with the least starting index.
Note : All characters are in Lowercase alphabets.
Example :
Input:
S = "timetopractice"
P = "toc"
Output:
toprac
Explanation: "toprac" is the smallest substring in which "toc" can be found.
