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 temp = 0U;
    for(int i = 0; i < 8; i++)
    {
        temp |= (((val) << (i)) & (1U << 2U*i));
    }
    // (101 << 0) -> 101 & 001
    // (101 << 1) -> 1010 & 100
    // (101 << 2) -> 10100 & 10000 
    return temp;
}

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

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