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;
    for(int i = 0; i < 16; i++)
    {
        if(i % 2 == 0)
        {
            if((val >> (i/2)) & 1)
            {
                res = res | (1 << i);
            }
        }
        
    }
    return res;
   
}

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

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