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 final_res=0;
    for(int i = 0;i<8;i++){
        if(val&1){
            final_res |= (1<<(i<<1));
        }
        else {
            final_res &= ~(1<<(i<<1));
        }   
        val = val >> 1;
    }
    return final_res;
}

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

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