Linked list algorithms involve operations on linked lists, such as insertion, deletion, and traversal.

• Linked list algorithms are used to manipulate data stored in linked lists.

• Common operations include inserting a new node, deleting a node, and traversing the list.

• Examples of linked list algorithms include reversing a linked list, finding the middle node, and detecting a loop in the list.

Random number generators and Monte Carlo simulations can be used to estimate the value of Pi and other quantities.

• Monte Carlo simulations involve generating random numbers to estimate a value or solve a problem

• To estimate Pi, random points are generated within a square and the ratio of points inside a circle to total points is used

• Other quantities can be estimated using similar principles, such as estimating the a...read more

The task is to find the first petrol pump from which a truck can complete a full circle or determine if it's impossible.

• Iterate through each petrol pump and calculate the remaining petrol after reaching the next pump.

• If the remaining petrol is negative at any point, reset the starting pump to the next pump and continue.

• If the total remaining petrol at the end is non-negative, return the index of the starting pump.

Finding the greatest common divisor (GCD) of two given numbers 'X' and 'Y'.

• Iterate through each test case and calculate GCD using Euclidean algorithm

• Handle edge cases like when one of the numbers is 0

• Output the GCD for each test case

Implement a wildcard pattern matching algorithm to determine if a given wildcard pattern matches a text string completely.

• Create a recursive function to match the pattern with the text character by character

• Handle cases for '?' and '*' characters in the pattern

• Keep track of the current position in both pattern and text strings

• Return 'True' if the pattern matches the text completely, otherwise return 'False'

The ER Model is a conceptual data model that describes the data and relationships in a system using entities and their attributes.

• ER Model stands for Entity-Relationship Model

• It is used to represent the logical structure of a database

• Entities are objects or concepts in the real world that are represented in the database

• Attributes are properties that describe the entities

• Relationships define how entities are relate...read more
