解决报错：AddressSanitizer: heap-buffer-overflow

leetcode上报错：

==42==ABORTING

leetcode使用AddressSanitizer检查内存是否存在非法访问。报此错，主要是访问了非法内容。
解决方法：数组访问越界，导致此错，后来发现是在访问二维数组的边界row和col弄反了。。

【注意】
LeetCode系统在执行代码时，系统都会判断数组越界问题，并直接报错，根据经验leetcode在用到数组或指针时，做两种处理：

• 1.定义指针时，需要申请内存块，如 int* data = malloc(SIZE * sizeof(int));后面访问指针时，不要大于SIZE值的地址范围。
• 2.定义数组，如int data[SIZE] 后，访问数组时，不要大于SIZE值的地址范围。
