Truncate and drop are SQL commands used to remove data from a table.
Truncate removes all data from a table but keeps the structure intact.
Drop removes the entire table and its structure.
Truncate is faster than drop as it only removes data.
Drop cannot be undone while truncate can be rolled back.
Truncate resets the identity of the table while drop does not.
Examples: TRUNCATE TABLE table_name; DROP TABLE table_name;

What people are saying about Virtusa Consulting Services
Polymorphism is the ability of an object to take on many forms.
Polymorphism allows objects of different classes to be treated as if they are of the same class.
It is achieved through method overloading and method overriding.
Example: A parent class Animal can have child classes like Dog, Cat, and Bird. Each child class can have its own implementation of the method 'makeSound', but they can all be called using the sa...
SQL commands for inserting, updating, and deleting data from a table.

UPDATE table_name SET column1 = new_value1 WHERE condition;
DELETE FROM table_name WHERE condition;
Given an 'M x N' matrix, print all the possible paths from the top-left corner to the bottom-right corner. You can only move either right (from (i,j) to (i,j+1)) or down...
Print all possible paths from top-left to bottom-right in a matrix by moving only right or down.
Use backtracking to explore all possible paths from top-left to bottom-right in the matrix.
At each cell, recursively explore moving right and down until reaching the bottom-right corner.
Keep track of the current path and add it to the result when reaching the destination.

Find all possible paths for a rat in a maze from source to destination.
Use backtracking to explore all possible paths in the maze.
Keep track of visited cells to avoid revisiting them.
Explore all possible directions (up, down, left, right) from each cell.
Add the current direction to the path and recursively explore further.
If the destination is reached, add the path to the list of valid paths.

Tip 1 : Competitive programming plays a major role when you are appearing for coding rounds as a fresher. In the coding rounds, you won't get direct problems copied from Geeksforgeeks or Leetcode. You would be required to use your logical thinking to go ahead in the process. This is where competitive programming helps.
Tip 2 : Coding rounds are all about Coding + Timing. Most people fail to excel due to the pressure of a timer ticking on your head. So, instead of just solving problems, try to participate in timed contests. This will help you be used to the pressure of the timer.
Tip 3 : Many big companies like Microsoft, Amazon, and even Google expect you to be good at standard problems. So, once you are done with coding round by your logical skills and competitive programming, you must be well versed with some standard problems in order to excel.
Application resume tips for other job seekersTip 1 : Make it short, crisp, and simple. It is always good to have a 1 pager resume.
Tip 2 : Resume must comprise of the following: Educational Qualifications, Technical skills, Projects, Work experience (if any), Achievements. Other than this, you may include some extra co-curricular achievements.
