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
    for(uint8_t rotate=1; rotate<=16; rotate++)
    {
       // printf("%u\n", &reg);
        if(reg==target)
        {
            return 1;
        }
        reg = (reg<<1) | (reg>>(16-1));
        reg &= 0xFFFF;
    }
    return 0;
}

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