33. Detect Circular Pattern Match

#include <stdio.h>
#include <stdint.h>

uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    for( uint8_t au1_ForC=0; au1_ForC<16; au1_ForC++ )
    {
        target = (target << au1_ForC) | (target >> (16 - au1_ForC));
        if( reg == target )
        {
            return 1;
        }
    }
    return 0;
}

int main() {
    uint16_t reg, target;
    scanf("%hu %hu", &reg, &target);
    printf("%hhu", is_circular_match(reg, target));
    return 0;
}
