long int T,i;
the RE that u r getting is due to the wrong use of scanf…it should be:-
also rethink on ur logic…
why did you divide by 5?
for example 6! has 1 zero and 10! has 2 zeros.Bcz we had 1 multiple of 5 in 6! and 2 multiples of 5 in 10!.Since we can have 2 multiples of 2 for every multiple of 5 we can get a 10 with one multiple of 5.
with this logic see if u r getting the correct ans for 100…by ur logic it should be 20…but the ans is 24…see the sample test cases…
