I was wondering how to keep track of how many times a word is generated using random letters.
I would generate say 1000 random letters, and wanted to know how many times the word "hi" or "hello" appeared inside these random letters.

int Mask( int x )
{
} // Mask( )
This function should return an integer with a 1 corresponding to x's least significant 1 bit; read: x's rightmost 1. I can't use control structures, and I can only use the operands ! ~ | ^ & << >> and +. If anyone has any tips, I'd appreciate it.
