Bit Spreading Interleave Bits with Zeros

Code

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

uint16_t spread_bits(uint8_t val) {
    // Your logic here
    uint16_t sp = 0;
    for(int i = 0;i < 8;i++){
        uint8_t tmp = val & (1 << i);
        if (tmp == 0){
            continue;
        }
        sp |= 1 << (2 * i);
    }
    return sp;
}

int main() {
    uint8_t val;
    scanf("%hhu", &val);

    uint16_t result = spread_bits(val);
    printf("%u", result);
    return 0;
}
