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(int i=0; i<=15; i++)
    {
        //if(target == (reg<<i)|(reg>>(16-i)))
            //return 1;
        if (reg == target) return 1;
        // Perform 1-bit circular left rotation
        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;
}
