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 updated_val=0;
    int j=0;
    for(uint16_t i=0;i<16;i++)
    {
        if(i%2==0)
        {
    
        updated_val |=(1<<i) & ((val>>j)&1)<<i;
        j++;
        }

    }
    return updated_val;
}

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

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