New Year Chaos Solution - The Coding Shala

Home >> Programming Questions >> New Year Chaos New Year Chaos Problem Solution In this post, you will learn how to solve New Year Chaos Problem and implement its solution in Java. Problem:   It's New Year's Day and everyone's in line for the Wonderland rollercoaster ride! There are a number of people queued up, and each person wears a sticker indicating their initial position in the queue. Initial positions increment from at the front of the line to at the back.  Any person in the queue can bribe the person directly in front of them to swap positions. If two people swap positions, they still wear the same sticker denoting their original places in line. One person can bribe at most two others.  For Example, if n=8 and Person 5 bribes Person 4, the queue will look like this: 1,2,3,5,4,6,7,8. Fascinated by this chaotic queue, you decide you must know the minimum number of bribes that took place to get the queue into its current state. Inpu...

Graph Representation using Adjacency Matrix - The Coding Shala

Home >> Data Structures >> Graph Representation using Adjacency Matrix Graph Representation using Adjacency Matrix In this post, we will see how to represent a graph using the Adjacency Matrix. Generally, the Adjacency matrix is used to check if there is any edge available between two vertices or not. In the Adjacency matrix, we take a 2D array of size v*V, where V is the number of vertices in a graph and array[i][j] = 1 indicates that there is an edge between vertex i and j. The following example explains the Adjacency matrix of a graph: Graph Representation using Adjacency Matrix Java Program We have given the number of vertices 'v' and edges 'E' of a bidirectional graph. Our task is to build a graph through the adjacency matrix and print it. Example 1: Input: 5 7 0 1 0 4 1 2 1 3 1 4 2 3 3 4 Output: 0 1 0 0 1  1 0 1 1 1  0 1 0 1 0  0 1 1 0 1  1 1 0 1 0  Java Code: import java.util....

LeetCode - Crawler Log Folder Solution - The Coding Shala

Home >> LeetCode >> Crawler Log Folder  In this post, we will learn how to solve LeetCode's Crawler Log Folder problem and will implement Crawler Log Folder Java Solution. Crawler Log Folder Problem The Leetcode file system keeps a log each time some user performs a change folder operation. The operations are described below: "../": Move to the parent folder of the current folder. (If you are already in the main folder, remain in the same folder). "./": Remain in the same folder. "x/": Move to the child folder named x (This folder is guaranteed to always exist). You are given a list of strings logs where logs[i] is the operation performed by the user at the ith step. The file system starts in the main folder, then the operations in logs are performed. Return the minimum number of operations needed to go back to the main folder after the change folder operations. Input: logs = ["d1/","d2/","../","d2...

Java Method Overloading - The Coding Shala

Image
Home >> Learn Java >> Java Method Overloading Java Method Overloading Java class can have more than one method with the same name but different in parameters, known as Method Overloading. Question: What is the use of method overloading? Answer:  Suppose we want to perform some operation like an addition but addition can be performed between two numbers, three numbers or two floats or more. So instead of using different methods, we use the same name of the method with different parameters. This can increase the readability of the program. Method overloading can be achieved by changing numbers of arguments or by changing the data types. Example of Method Overloading in Java The following example explains Method Overloading: //Method Overloading example class Addition { public int add ( int a , int b ){ return a + b ; } public int add ( int a , int b , int c ){ return a + b + c ; ...

Maximum Absolute Difference - The Coding Shala

Image
Home >> Programming Questions >> Maximum Absolute Difference Maximum Absolute Difference InterviewBit Solution You are given an array of N integers, A 1 , A2, …, A N . Return maximum value of   f(i, j)   for all 1 ≤   i, j   ≤ N. f(i, j)  is defined as  |A[i] - A[j]| + |i - j| , where |x| denotes the absolute value of x. For example , A=[1, 3, -1] f(1, 1) = f(2, 2) = f(3, 3) = 0 f(1, 2) = f(2, 1) = |1 - 3| + |1 - 2| = 3 f(1, 3) = f(3, 1) = |1 - (-1)| + |1 - 3| = 4 f(2, 3) = f(3, 2) = |3 - (-1)| + |2 - 3| = 5 So, we return 5. Solution Here function f(i, j) = |A[i] - A[j]| + |i-j] can be written in four ways -  (A[i] + i) - (A[j] + j) -(A[i] - i) + (A[j] - j) (A[i] - i) - (A[j] - j) (-A[i] - i) + (A[j] + j) = -(A[i] + i) + (A[j] + j) we just have to store minimum and maximum values of expressions  A[i] + i  and  A[i] - i  for all  i.
