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 ret = 0;
    ret |= ((val >> 0) & 1) << 0;
    ret |= ((val >> 1) & 1) << 2;
    ret |= ((val >> 2) & 1) << 4;
    ret |= ((val >> 3) & 1) << 6;
    ret |= ((val >> 4) & 1) << 8;
    ret |= ((val >> 5) & 1) << 10;
    ret |= ((val >> 6) & 1) << 12;
    ret |= ((val >> 7) & 1) << 14;
    return ret;
}

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

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