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 result = 0;
    uint16_t result_mask = 1;
    uint8_t val_mask = 1;
    for(int i = 0; i< 16; i++){
        if(i % 2 == 0){
            // bn
            if(val & val_mask){
                result = result | result_mask;
            }
            val_mask = val_mask << 1;
        }
        result_mask = result_mask << 1;
    }
    return result;
}

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

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