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.

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...

What is a Processor?

Smartphones have been the most important part of our lives. We have seen the evolution of our handsets. First we saw landlines which were mess of tangled wires then we saw mobile phones which is successor of landlines. They were portable devices from which you can make calls then we witnessed emergence of Smartphones which were considered as portable computers which also allows us to make calls. What is a Processor? Underneath that touchscreen display there is a full- fledged computer that commands your apps so that they function properly. A processor executes what you want your smartphone to do or in other word you can say processor is brain of computer. there is Exynos, Snapdragon, quad-core octa-core etc. What is a core? It is an element of surprises. They are present inside processor and are responsible for reading the command and executing them. First devices came with single core processor but later on scientists invented more advanced processors such as dual core , So...

Group Anagrams – Python Solution Explained

Problem Overview The Group Anagrams problem is a common challenge in coding interviews and competitive programming. The goal is to group a list of strings such that all anagrams are placed in the same group. Anagrams are words that contain the same characters but in different orders. For example, given the input ["eat", "tea", "tan", "ate", "nat", "bat"] , the expected output is [['eat', 'tea', 'ate'], ['tan', 'nat'], ['bat']] . Approach and Solution In this blog post, we'll discuss an efficient solution using Python's built-in data structures. The provided code uses a dictionary to group the anagrams. Here’s a step-by-step explanation of the approach: Code Breakdown Explanation Initialization: We use defaultdict from the collections module to create a dictionary ( hm ) where each key will map to a list of anagrams. This is useful because it automatically initializes ...
