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 result = 0;
    for (int i=0; i < 8; i++){      // we want to iterate through the bits
        if (val & (1 << i)){        // check if each bit is 1
            result |= (1U << 2*i);  // if each bit is 1 set new position 2*i
        }
    }
    return result;
}

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

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