Bit Spreading Interleave Bits with Zeros

Code

#include <stdio.h>
#include <stdint.h>

uint16_t spread_bits(uint8_t val) {
    uint16_t num=0;
    for (int i=0;i<8;i++)
            num=(num<<2) | (val>>(7-i) & 1);
    // Your logic here
    return num;
}


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

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