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 num = 0;
   
    for(int i= 0 ; i<8;i++){
        uint8_t bit = (val >> i) & 1; 
        num |= (bit << (2 * i));
    }
    return num;
}

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

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