Hello,

I have a problem when I try to double the length of the array if it is already full.

For example,

array arr has length 5, and I want to insert 7 elements in it.

This is what should I get:

arr = [1, 2, 3, 4, 5, 6, 7]

length of arr = 10;

This is what I am getting:

[1717986918, 1075603046, 3, 4, 5, 6, 7]

malloc: *** error for object 0x100180: double free

This is the function:

```
void double_array_1d(int* arr, int length) {
int* temp_arr = new int[2 * length];
for (int i = 0; i < length; i++) {
temp_arr[i] = arr[i];
}
delete[] arr;
arr = temp_arr;
}
```

Any help is appreciated, thanks.
