8 out of 10 testcases failed. Isn’t my approach valid?
String Window testcases failed
First check if length of string is less than the length of given pattern, if yes then "no such window can exist ".
Store the occurrence of characters of given pattern in a hash_pat[].
Start matching the characters of pattern with the characters of string i.e. increment count if a character matches
Check if (count == length of pattern ) this means a window is found
If such window found, try to minimize it by removing extra characters from beginning of current window.
Update min_length
Print the minimum length window.
this is simplest approach
just take two pointer strt and end
move the end pointer util the all characters of str2 will found in str1
then store that lenght
then move the strt pointer
do the above step util the whole string is traversed
