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_val = 0;
    for (int i=0; i<8; i++){
        /*Check every bit*/
        if ((val >> i) & 1) { // Spread the bit since it is 1
            spread_val |= (1U << (2*i));
        }
    }

    return spread_val;
}

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

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