Yes,for example "Divisors of 42 are : 1, 2, 3, 6, 7, 14, 21, 42" then you take square of each divisor and finally take sum by adding up all the squared divisors of 42 and test it to see if it is square by taking square root.
1, 2, 3, 6, 7, 14, 21, 42 -> 1^2 + 2^2 + 3^2 + 6^2 + 7^2 + 14^2 + 21^2 + 42^2 = 2500 = 50 * 50 which is square.

true
Description is so short and doesn't really define what's actually "line" in problems.

lol these lines make me laugh so hard
if(totok == NULL) printf("ya fucked up malloc\n");
if(output == NULL) printf("ya fucked up malloc\n");
if(outputStreets == NULL) printf("ya fucked up malloc\n");
if(outputNumbers == NULL) printf("ya fucked up malloc\n");

Funny why I never think of this. Nice One!
