Detect Circular Pattern Match

Code

#include <stdio.h>
#include <stdint.h>
// uint16_t rotate_left(uint16_t reg)
// {
//     return (reg<<1)|(reg>>15);

// }


uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    // Your code here
    uint8_t count = 0;
    uint16_t temp;
    while(count < 16){
        count++;
        if(reg == target){
            return 1;
        }
        // reg = rotate_left(reg);
        reg = (reg<<1)|(reg>>15);
    }
    return 0;
}

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