TUF+ launching on 7th August, are you excited about it? If you are wanting to give hate for us bringing a paid model. Here are a few things you must read. 1. if you are an engineer, you know the server cost to run takeuforward website which has 13M+ views every month. 2. TUF stays free, so should not affect anyone, just blink an eye. It will be a course, but not a course! Miles apart from what others are providing you..

one mistake in optimal approach solution : int trap(vector& height) { int n=height.size(); int unit=0; int i=0,j=n-1; int l_max=0,r_max=0; while(i!=j) { if(height[i]height[i]) unit=unit+l_max-height[i]; else l_max=height[i]; i++; } else if(height[j]height[j]) unit=unit+r_max-height[j]; else r_max=height[j]; j--; } else { l_max=max(l_max,height[i++]); } } return unit; }

[@anush_20]

In the push in queue using LL, in the else condition, end->next = temp; But after, the end should also be pointing to temp right?

Correct me if I'm wrong but the queue using array implementation in the video is actually the implementation of a circular queue right? instead of the traditional queue implementation

yes
