Hey! In the last contest I was getting TLE on a problem, I thought my solution was not optimal, now I tried to solve it but using a loop to clear all elements of the array instead of "memset" -which I was using- and I got AC!! So which one is better ?? UPD: found that the TLE then using "memset" was because there was a mistake with the size of the array (which I don't know why I got TLE not RTE or something like that!!). But anyway, the time for the solution when using a "for" loop is like " 156 ms ", while it is " 1294 ms " when using "memset !!!
