33. Detect Circular Pattern Match

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

uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    // Your code here
    uint32_t combined = reg | (reg <<16);
    for(uint8_t i=0; i<16; i++)
    {
        if(target == ((combined >>i) & 0xFFFF))
        {
            return true;
        }
    }
    return false;
}

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