one of the rare videos where the instructor not only is good at solving but also, and more importantly in this case, explaining the solution

I did not understand why use the second while loop?

[@AanchalSharma-e4e]

please upload more questions

I will!

[@Jaffar87]

are u going to do all leetcode questions

[@LeetCodeUniversity]

The plan is to do Blind 75 list and then do pattern based questions

[@Jaffar87]

Thanks it would be nice if you do all the leetcode questions

[@musamehdiyevv]

Thank you for the explanation. I think this code is simpler:
class Solution {
public void merge(int[] nums1, int m, int[] nums2, int n) {
int p = m + n - 1;
int p1 = m - 1;
int p2 = n - 1;
while (p2 >= 0) {
if (p1 >= 0 && nums1[p1] > nums2[p2]) {
nums1[p] = nums1[p1];
p1--;
p--;
} else {
nums1[p] = nums2[p2];
p2--;
p--;
}
}
}
}

[@kousthubganugapati7193]

will this work for every array

[@LeetCodeUniversity]

For sure!

[@flyguynoaholdksa5461]

Nice

[@alastairhewitt380]

Fantastic explanation
Edit:
In the while loop, if I only write p1 >= 0, then I get an index out of bound error, but if I include the logic for p1 & p2 then the code up until that point works properly.
I am not really sure why that is since m & n are both 3. Can someone please help explain what I am not seeing? To me it is the same thing
