The questions of the DSA Sheet have been handpicked from repeated interview questions and they range from lower to highest levels of difficulty.
If this strikes your interest, we have handpicked a few questions from the DSA Sheet ourselves that you might encounter in coding interviews.
How to solve the Love Babbar DSA Sheet problems?
To solve the Love Babbar DSA cracker sheet, we have a few prerequisites that the candidates must be acquainted with before downloading the pdf.
● You must be well acquainted with the basics of DSA i.e Data Structures and Algorithms
● You should also have proper hold of at least one coding language i.e Java or C++
If you have these pointers down, then check out these recurring questions from different sections of the DSA Sheet such as algorithms, binary trees and array interview questions.
Love Babbar DSA Sheet Questions
Let's solve some DSA cracker Sheet problems picked from different coding interviews.
Problem Statement:
You have been given a string or an array. Reverse the string or array using algorithms.
Answer Key:
The easiest way to tackle this problem would be implementing the Iterative Approach. Here's how the algorithm for the approach would work:
● Begin with initialising the starting and the last indices of the array with start = 0 and end = n-1
● Next up, create a loop for swapping these indices i.e arr[start] and arr[end] need to be swapped
Problem Statement:
You have been given an array of randomly ordered positive and negative numbers. Your task is to rearrange this array so that all of the negative numbers exist before the positives.
Answer Key:
One of the effective approaches for solving this problem would be using the sorting/naive algorithm. Here's how that would work:
● Run the sort(arr) function for the entire length of the array and let the program take care of the task
● Once the array is sorted, print the results in a sorted format
Problem Statement:
You have been given a randomly ordered array of time intervals. Your task is to figure out the similar time intervals, merge them and print the output.
Answer Key:
A simple nested loop approach would certainly work for solving this problem statement. Check out the implementation of the algorithm for this approach:
● Begin with the first interval and start comparing it to the rest of the time intervals and check for any overlaps
● In case an overlap is found, remove it from the list and continue the process until all the time intervals are visited
Problem Statement:
You are provided a doubly linked list. Your task is to reverse the list.
Answer Key:
In order to reverse the given doubly linked list, follow the algorithm mentioned below:
● Start by traversing the linked list by using a pointer
● Next up, you are required to swap ll the previous and the next pointed for all the nodes of the linked list
● Finally, you need to change the first pointer of the linked list and print the output
Problem Statement:
You have been given a circular linked list. Split it into two halves.
Answer Key:
The following algorithm would work efficiently for solving this problem:
● Using the tortoise and hare algorithm, store the values of the mid and last pointers of the given linked list
● Next up, make the second half as circular
● Do the same with the first half of the list
● Create head pointers for both the lists
● Print the output as a circular linked list
Winding Up
One of the key aspects to note before downloading the Love Babbar DSA cracker sheet is that you must be fluent in at least one coding language such Python, Java or C++
If you have that down, then this DSA Sheet is more than efficient to help you out in preparing important questions such as DSA problems, OOPs concepts and tackling the array interview questions!
