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 final_val=0U;
    uint8_t mask=1U;
    for(int i=0; i<8;i++)
    {
        uint16_t final_mask=1U;
        if((val &mask)!=0){
            final_mask<<= (2*i);
            final_val |= final_mask;
        }
        mask<<=1;
    }
    return final_val;
}

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

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