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  spread_bits;
    
    for(uint16_t i=0 ; i< 8; i++)
    {
      if(val & (1<<i)){
        spread_bits |= (1<<(2*i));  
    }
    else{
        spread_bits &= ~(1<<(2*i));
    }
    }

    return spread_bits;
}

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

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