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;
    res |= 1 & val;
    res |= 4 & (val << 1);
    res |= 16 & (val << 2);
    res |= 64 & (val << 3);
    res |= 256 & (val << 4);
    res |= 1024 & (val << 5);
    res |= 4096 & (val << 6);
    res |= 16384 & (val << 7);
    return res;
}

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

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