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 s;
    for  (int i = 0; 8>i; i++){
        if (val &(1<<i)){
            s |= (1<<2*i);
        }
    }
    return s;
}

int main() {
    uint8_t val;
    scanf("%hhu", &val);
    uint16_t result = spread_bits(val);
    printf("%u", result);
    return 0;
}
