Showing why we should give shoring involves demonstrating the necessity and benefits of providing support to the railway infrastructure.
Shoring is essential for maintaining the structural integrity of railway tracks and preventing accidents.
It helps in stabilizing the ground, protecting against erosion, and ensuring safe passage for trains.
By showcasing the potential risks and consequences of not providing shoring, sta...
The formula for steel calculation involves determining the weight of steel required based on the dimensions and density of the material.
Calculate the volume of steel needed by multiplying the length, width, and height of the structure.
Determine the density of the steel material being used.
Multiply the volume by the density to get the weight of steel required.
Consider any additional factors such as wastage or safety mar

Repeat this process for all elements in the array
Continue this process until no more swaps are needed

Hashmap is a data structure that stores key-value pairs and allows constant time access to values based on their keys.
Hashmap uses a hash function to map keys to indices in an array.
Collisions can occur when multiple keys map to the same index, which can be resolved using techniques like chaining or open addressing.
Examples of hashmap implementations include Java's HashMap class and Python's dict type.
Inheritance is a mechanism in object-oriented programming where a new class is created by inheriting properties of an existing class.
Inheritance allows code reuse and promotes code organization.
The existing class is called the parent or superclass, and the new class is called the child or subclass.
The child class inherits all the properties and methods of the parent class and can also add new properties and methods.
