Detect Circular Pattern Match

Code

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



uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    // Your code here
    uint16_t tmp = 0;
    uint16_t mark = 0;

    for(int n = 0 ; n < 16 ; n++)
    {
        if(target == reg)
            return 1 ;
        
        tmp = (reg & 0x01)<<15;
        reg = (reg>>1) | tmp;
    }

    return 0;
}

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