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=0,a,b;
    char arr[60];

    scanf("%d%d",&a,&b);
    getchar();
    for(i=0;i<a;i++){
        scanf("%c",&arr[i]);
    }
    arr[b-1]=(arr[b-1]-'A')+'a';
    for(i=0;i<a;i++){
        printf("%c",arr[i]);
    }
    printf("\n");

    return 0;
}

```
