About the duplicates characters in the string2

[luckypavan]

if there are duplicate characters in the string 2 the should we consider only one occurrence or duplicate characters are also should be considered

[saurabh_singhCmn (Saurabh Singh)]

you should consider duplicate characters as different characters i.e. if the string 2 is aabc, then you need to find a shortest string of string a that contains 2a’s, 1b and 1c.
