Juspay Coding Questions and Answers with Tips for Freshers 2025

Juspay, a leading fintech company, is known for its rigorous recruitment process that includes coding rounds to assess the technical skills of potential candidates. If you're a fresher aspiring to join Juspay, understanding their coding test pattern, practising relevant coding questions, and knowing how to approach them are essential for success. 

This article will provide you with everything you need to know about the Juspay coding questions, sample coding problems, and interview tips that will help you excel in the hiring process.

What is the Juspay Coding Rounds?

The coding round at Juspay is one of the key stages of their hiring process, designed to evaluate your problem-solving and programming skills. Whether you're applying for a developer position, an internship, or a full-time role, the coding round will test your ability to write clean, efficient, and optimised code under time constraints. 

What to Expect in Juspay Coding Tests? 

Juspay's coding test is typically divided into the following sections:

Data Structures & Algorithms

These questions test your understanding of fundamental data structures (arrays, linked lists, stacks, queues, trees, graphs) and algorithms (sorting, searching, dynamic programming, recursion).

Problem-Solving

You may be given real-world problems related to the fintech industry or algorithmic challenges that require innovative solutions.

Coding Efficiency

The ability to write optimal, efficient code within the given time limit is crucial.

Online Coding Platform

Juspay typically conducts these rounds on platforms like HackerRank or CodeSignal, which means you’ll be expected to write code and test it in a timed environment.

Key Coding Questions You Might Encounter

Here’s a look at some of the typical coding questions in the Juspay coding round:

1. Algorithmic Challenges

• Sorting & Searching Problems: e.g., "Given a list of transactions, write an efficient algorithm to sort them based on transaction dates."
• Dynamic Programming: e.g., "Implement an algorithm to find the longest subsequence of transactions where the total value is maximised."

2. Data Structures Problems

• Linked Lists: e.g., "Reverse a singly linked list in place."
• Binary Trees: e.g., "Find the height of a binary tree or check if a binary tree is balanced."

3. Real-World Scenarios

• Payment Gateway Simulation: e.g., "Write a function that simulates a basic payment transaction with checks for valid card number, CVV, and expiry date."
• Optimisation Problems: e.g., "Optimize the storage of transaction data with limited memory."

Selected Juspay Coding Test Questions & Answers

Problem Statement 1

You are given a string with alphabets. You need to convert the string to lowercase and check if the string is a palindromic one.

If the string is a palindrome, print the length of the palindromic string. If that string is a non-palindromic one, print the ASCII value of the first character of the alphabet in the given string.

Input Format

The input consists of a single string containing only alphabetic characters (both uppercase and lowercase).

Output Format

Print the Length of the palindromic string if it is a palindrome after performing the above operations. Otherwise, print the ASCII value of the first character.

Solution C++

Solution Python

Problem Statement 2

A matrix diagonal is a diagonal line of cells starting from some cell in either the topmost row or leftmost column and going in the bottom-right direction until reaching the matrix's end.

For example, the matrix diagonal starting from mat[2][0], where mat is a 6 x 3 matrix, includes cells mat[2][0], mat[3][1], and mat[4][2].

Given an m x n matrix mat of integers, sort each matrix diagonal in ascending order and return the resulting matrix.

Input Format

The first line contains two integers, M and N, representing the number of rows and columns in the matrix.

The next M lines each contain N integers, representing the elements of the matrix mat. Each line corresponds to a row in the matrix.

Output Format

Print the Diagonally sorted matrix. Each row of the matrix should be printed on a new line.

Problem Statement 3

Ronnie is given N coins, each having some value, and provided with a task. In the task, Ronnie has to first arrange the coins in a sorted fashion. After that, he has to set the coins in the form of a tree.

After forming the tree, he has to find the maximum possible absolute value of the difference in that tree, as that will be the profit he will make.

Your task is to help Ronnie find the maximum profit.

Input Format

The first line of the input contains an integer N denoting the number of nodes.

The next line of the input contains N integers.

Output Format

Display the maximum profit that Ronnie can make.

Solution C++

Solution Java

Solution Python

Problem Statement 4

Archan is a professor at the Academy Of Technology. One day, he calls his student Niladri to play an interesting game. He asked Niladri to imagine an empty bucket. He then does k queries. In each query, he asks Niladri to do either of the following operations:

Add a number v to the bucket.

Get the median of all numbers added to the bucket.

Niladri needs to answer Archan only in the type 2 query. Can you help Niladri to do so?

Note: Answer within one decimal place of the actual answer will be accepted.

Input Format

The first line contains k, which is the number of queries that Archan will ask. K subsequent lines follow.

Each line contains the type of query whether it is “add” or “get” followed by a space and then the value v if it's an “add” query.

The first query will always be “add”. There will be at least one “get” query.

Output Format

The output contains several lines(one or more), each denoting the answer to each “get” query.

The answer should always be formatted to one decimal place.

Solution C++

Solution Java

Solution Python

Problem Statement 5

A park in the city has N trees numbered from 1 to N connected by N-1 pavements. This structure resembles a binary tree rooted at tree '1' where trees represent the vertices and pavements represent its edges.

Each tree has a fruit on it. Some of the fruits are sweet, while others are bitter. The ith tree (1 <= i <= N) has a fruit of sweetness ai. If the fruit is bitter, the value of ai will be negative.

You went to the park to collect fruits. You cannot visit any tree more than once and will have to collect the fruit from each tree you visit from the starting position of your choice. You can decide to return home with all the fruits you collected at any point. Find the maximum value of sweetness that you can collect.

Input Format

The first line contains a single integer N, denoting the number of trees in the park.

The second line contains N integers a1, a2, …, aN, denoting the sweetness of fruit on each of the N trees.

The next N lines describe the binary tree structure of the park. The ith line contains two integers, li and ri, denoting the indices of the left and right children of the ith vertex, respectively. If some child doesn't exist, then the number “-1” is set instead.

It is guaranteed that the given graph is a binary tree rooted at vertex 1.

Output Format

Print a single integer the maximum amount of sweetness you can get from the collected fruits.
