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(void)
{
	int s1, s2, max, cnt;
	int i;
	
	
	while (1) {
		scanf("%d%d", &s1, &s2);
		if (s1 == 0 && s2 == 0)
			break;
		max = s1 + s2; cnt = 0;
		for (i = 1; i < 5; i++) {
			scanf("%d%d", &s1, &s2);
			if (max < s1 + s2) {
				max = s1 + s2; cnt = i;
			}
		}
		switch (cnt) {
			case 0: printf("A "); break;
			case 1: printf("B "); break;
       		case 2: printf("C "); break;
			case 3: printf("D "); break;
			case 4: printf("E "); break;
		}
		printf("%d\n", max);
	}
	return 0;
}```

C Code:

			break;
		max = s1 + s2; cnt = 0;
		for (i = 1; i < 5; i++) {
			scanf("%d%d", &s1, &s2);

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(void)
{
	int s1, s2, max, cnt;
	int i;
	
	
	while (1) {
		scanf("%d%d", &s1, &s2);
		if (s1 == 0 && s2 == 0)
			break;
		max = s1 + s2; cnt = 0;
		for (i = 1; i < 5; i++) {
			scanf("%d%d", &s1, &s2);
			if (max < s1 + s2) {
				max = s1 + s2; cnt = i;
			}
		}
		switch (cnt) {
			case 0: printf("A "); break;
			case 1: printf("B "); break;
       		case 2: printf("C "); break;
			case 3: printf("D "); break;
			case 4: printf("E "); break;
		}
		printf("%d\n", max);
	}
	return 0;
}```
