内存溢出错误

问题：AddressSanitizer: heap-buffer-overflow on address 0x602000000040 at pc 0x000000406b5e bp 0x7ffc15cc0320 sp 0x7ffc15cc0318

解决方法：注意循环中的上下是否越界；注意数组是否越界

int n = nums.size();
int idx = 0;
while(idx < n){
     idx ++;  //idx会越界
     cout <<nums[idx];    
}    

int n = nums.size();
int idx = 0;
while(idx < n){
     cout <<nums[idx];
     idx ++;   
}
