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>
 
int main() {
	
	int i,j;
	char Masu[4][4];
	
	for( i=0; i<3; i++ ){
		for( j=0; j<3; j++ ){
			if( i != 0 && j == 0 ){
				scanf("%*c%c", &Masu[i][j]);
			} else {
				scanf("%c", &Masu[i][j]);
			}
		}
	}
	printf( "%c%c%c\n", Masu[0][0],Masu[1][1],Masu[2][2] );
	return 0;
}
 ```
