33. Detect Circular Pattern Match

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

uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    uint16_t temp;
    uint8_t i = 0u;
    while(i<16)
    {
        temp = reg>>1;
        reg = reg<<15 | temp;
        if(reg == target)
        {
            return 1;
        }
        i++;

    }
    return 0;
}

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