MIKe and hashTrick

#1

codeLink : https://ide.codingblocks.com/s/186607
my code is showing some errors which I am unable to understand please , correct it and specify my error

#2

probably an index out of bound is giving an error
hash array need to be of size max+1 instead of max since in the next line
we are trying to access till <= MAX

long long *hash = new long long[MAX+1];
for (long long i = 0; i <= MAX; i++)
hash[i] = -1;

i dont see no other error.
