33. Detect Circular Pattern Match

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

uint8_t is_circular_match(uint16_t reg, uint16_t target) {
    // do a while loop for length of register, so here, 16 
    
    uint8_t result = 0; 

    for (int i = 0; i < 16; i++) { 
        if (reg == target) { 
            return 1; 
        }
        reg = (reg << 1) | (reg >> (16 - 1));
    }
    return 0;
}

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