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;
    for(int i=0;i<8;i++){
        if((val>>i)&1){
            result|=(1<<(2*i));
        }
    }
    return result;
}

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

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

Solving Approach

first take 16bit zero, now check the set bits in val at what position , now set the bits at the result at (2*pos)
