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 value = 0;
    uint16_t mask_16  = 1;
    uint8_t mask_8 = 1;
    for(int i = 0; i < 8; i++)
    {
        if(val & mask_8)
        {
            value |= mask_16;
        }
        mask_8 <<= 1;
        mask_16 <<= 2;
    }
    return value;
}

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

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