Bit Spreading Interleave Bits with Zeros

Code

#include <stdio.h>
#include <stdint.h>

uint16_t spread_bits(uint8_t val) {
    // Your logic here
    int i = 0, j =0;
    uint16_t temp = 0; 
    for(i=0; i<16; i++)
   {
    if(i==0)
    {
        temp |=val&(1<<j);
        
    }
    else if(i%2 == 0)
    {
        j++;
        if(val&(1<<j))
        {
            temp |= (1<<i);
        }
    }
   } 
    return temp;
}

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

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