Path Guide





What if you are new in your locality and you are not that much familiar with the streets. What will you do? The only answer in your mind is using navigation device, but what if you don’t have any source of internet connectivity, what would you do then? Seeing right through this problem Microsoft took an initiative by launching a brand new app. We can call it offline version of GPS. The name of App is Path Guide.

How does it works?Unlike GPS which shows the precise outlining of the area for navigation using Internet connectivity. Path Guide allows you to navigate your streets without using GPS. The app doesn’t need the Wi-Fi either and is very useful for indoor navigation.


The app launched in available only for android users on Google Play Store. The Path guide app uses sensors on your phone to record every movement in a particular area, or even in the city. Path Guide app allows users can produce maps of buildings and permits them to make these maps public, allowing other users to search and travel their way throughout buildings. Path Guide app can also be utilized in multiple scenarios like recording every step you take and distance you traveled within the building. The app also enables users to record audio, notes, and images which will help others who use the maps later. The app can be downloaded from Google Play Store and Apkmirror.

Here's the description of Microsoft's Path Guide on Play Store:

"Path Guide is a completely map-free, infrastructure-free, plug-and-play indoor navigation service. It explains the ubiquitous geomagnetism and natural walking patterns to guide users to destinations along a path collected by an earlier traveller."

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...

1456, Maximum Number of Vowels in a Substring of Given Length

Hi, folks today I am here with an interesting coding problem from Leetcode. *To directly go to the question please click here. So I will walk through the solution. It will be a brute force and an optimized way solution. I will be explaining the optimized way solutions in depth. # Intuition For any substring of length k, we need to find how many vowels are there in it and provide the highest count of all counts of vowels in a substring. Test Case 1 Input k = 2 and s='asjdee' Output - 2 Explanation: As for substring of length k=2, in the string 's' we have 'ee' when the length is k and the vowels count is 2 Test Case 2 Input k=3 and s='aasdiisdwe' Output - 2 Explanation - For all the substrings with length k = 3 we have 'aas' and 'dii' with 2 vowels each in it. Brute Force - Looping (twice) - Gives TLE (Not recommended) # Approach Create a hashmap (dictionary) with all the vowels in it. Loop through the string till len(s)-k element of strin...

2125. Number of Laser Beams in a Bank

Hi Guys, Today is 3 January 2024 and below is the solution for problem of the day So, the question we have is Number of Laser Beams in a Bank .  In this we have to find total number of lasers. So just imagine it as we have to find number of lines connecting the dots.  so if there are 2 dots. we will have one line, if we have 3 dots we will get 3 lines, and so on... Now relate the above provided example, let's relate this to our problem statement.   We have 4 walls, first wall has 3 lasers, second wall has 0 lasers, third wall got 2 lasers and last wall has 1 laser. So as i suggested we need to connect dots so make sure to only join adjacent dots. So lasers from 1 and 3 wall  will connect to each other (6 lasers) and wall 3 and 4 will connect to each other (2 lasers). So total of 8 lasers, which is the required output anyways. class Solution : def numberOfBeams ( self , bank : List[ str ]) -> int : val = 0 # Initialize a variable `val` to store th...
