Given the following C code and assembly code, your task is to generate highly optimized x86-64 assembly code.
C Code:

```c
#include<stdio.h>
#include<string.h>
int main(){
  char s[50],t[50];
  scanf("%s%s",s,t);
  int i;
  for(i=0;i<strlen(s);i++){
    printf("%c",s[i]);
    if(i<strlen(t))printf("%c",t[i]);
  }
  return 0;
}
