Bit Spreading Interleave Bits with Zeros

Code

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

uint16_t spread_bits(uint8_t val) {
    // Your logic here
    uint8_t arr[8]={0};
    uint16_t result=0;
    for( int i=0;i<8;i++)
    {
        if((val>>i)&1) arr[i]=1;
    }
    for(int i=0;i<8;i++)
    {
        if(arr[i])
        result|=(1<<(i*2));
    }
    
    return result;
}

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

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