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 temp1 = reg,temp2 = reg;
    if(reg == target)
    {
        return 1;

    }else
    {
        for(int i = 1; i < sizeof(target) * 8; i++)
        {
            temp2 = ( temp1 >> 16-1 ) & 1; // 1101 . 0001    1011 0111
            temp1 = temp1 << 1;            // 1101 , 1010    0111 1110     : 1011
            temp1 = temp1 | temp2;         // 1011
            if(temp1 == target)
            {
                return 1;
            }
        }
    }
    return 0;
}

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