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
    int i = 0;
    uint16_t reg1 = reg;
    if(target == 0) return 0;
    for(i = 0; i<16; i++){
        if((reg1 & target) == target)
            return 1;
            reg1 = ((reg1<<1) |((reg1 & 0x8000)>>15));
           
            
    }
    reg1 = reg;
    for(i = 0; i<16; i++){
        if((reg1 & target) == target)
            return 1;
        reg1 = ((reg1>>1) |((reg1 & 0x0001)<<15));
            
    }
    
    return 0;
}

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