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 i=0; i < 16;i++)
    {
        reg = ( reg << 1) | ( reg >> (16 -1));
        if(reg == target)
        {
            return 1;
            break;
        }
    }
    return 0;
}

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