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

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

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