What is the meaning of Power Symbol?

Have u ever noticed the power button?

We find it as circle with a vertical line. The power button is used to turn device on or off. The symbol is believed to have originated as technology advanced, and the term on/off was replaced by universal number 1 and 0. The number were derived from Binary Number System in which 1 stands for power on and 0 indicates power off. To create the symbol "1" & "0" were merged with each other, to bypass language barriers.

1721 - Swapping Nodes in a Linked List.

Hi, Today we will be solving leetcode qs 1721 - Swapping Nodes in a Linked List. This qs is really simple. We need to swap the nodes placed at k distance from the start and end of the Linked List. So let's suppose you have a Linked List input as follows: 1 -> 2-> 4 -> 5 -> 7 -> 8 -> 10-> 9 and you are given a k = 2, so the output should be 1 -> 10 -> 4 -> 5 -> 7 -> 8 -> 2 -> 9 so how do we achieve it??? Intuition The most brute force solution one can think of is using Array data structure. For that, we will traverse through linked List and store all the elements in the Array, swap the two numbers and again insert it in theLinked List again. Not bad, but let's deal with it, it is not the optimal solution and far from being as an acceptable solution in interviews. So what can we done instead of that??? Let's try to look deep into the working of Linked List first and how do we traverse it. Linked List is a linear data structure that...

1235. Maximum Profit in Job Scheduling

Hi everyone, Today's post is little bit intriguing to me as it took me some time to get t the solution. I have been out of practice for a bit so I was not able to do it in the DP. I didn't want to copy the code. Though i understood the code after i checked its solution in the discussions. Anyways, i tried to do it with heap and with some thinking I was able to do it and with my surprise It performed real well. I would like to jump to the solution but first I would like to explain a little bit about heaps so you can get better understanding of the code. A heap is like a special type of list where the smallest (or largest) item is always at the front. Think of it like a priority line at a theme park, where the person with the highest priority goes to the front. There are two types of heaps: Min Heap: The smallest item is at the front. It's like standing in a line where the shortest person is always at the front. Max Heap: The largest item is at the front. It's like stand...
