hello @atul51

u have misunderstood the problem.
u cannot pick few characters of the string and discard the rest of the characters.
here in the question u can either pick the complete string or discard it compeltely.

for example->
aaaa b
here answer will be 1 (string b). but urs solution will print 2. because it will pick a from the first string and b from the second.
whcih is wrong.
