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 ketqua = 0;
    
    for(int i = 0; i < 8; i++)
    {
        uint16_t temp = val & (1u << i);
        ketqua |= (temp << i);
    }
    
    return ketqua;
}

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

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