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,n=0;
    uint16_t result=0;
    for (i=0;i<16;i++){
        if (i==0) {
            if((val&(1<<n)) ==0)  result &= ~(1<<i);
            else result |= (1<<i);
            n+=1;
        }
        else if((i%2)==0) {
            if((val&(1<<n)) ==0) result &= ~(1<<i);
            else result |= (1<<i);
            n+=1;
        } 
        else result &= ~(1<<i);
    }

    return result;
}

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

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