Round duration - 120 minutes
Round difficulty - Hard

This round was very difficult. I never do these much difficulty level of coding questions. But i give my best, and just do every questions by using step by step process.

Q2. BFS in Graph
You are given an undirected and disconnected graph G(V, E) having V vertices numbered from 0 to V-1 and E edges. Your task is to print its BFS traversal starting from the 0th vertex.
BFS or ...read more
Ans. Using queue
Let us consider a function BFS that accepts a list of edges, EDGES, and the number of vertices VERTEX as a parameter and do: 
1. Create ADJACENCYMATRIX from EDGES.
2. Define a boolean array VISITED to store nodes that are already visited.
3. Iterate over VISITED[i] for each 0<= i < VISITED.LENGTH, and check:
   1. If VISITED[i] is FALSE, call BFSHELPER function for ADJACENCYMATRIX, i and VISITED.
Now, the function BF...read more

Q3. Sort a stack
Given a stack, sort the elements inside that stack in ascending order using only push and pop operation. You can use one additional stack only.
For eg.
Input Stack :  5 (top)

Round difficulty - Easy

This round is also coding round in this round we have a small video call interaction too, in which hr ask few questions to only those whose coding question is correct.

Q1. Next smaller Palindrome
You are given a number 'N' in the form of a string 'S', which is a palindrome. You need to find the greatest number strictly less than 'N' which is also a pa...read more
Ans. Brute Force
• Given the fact that the input number is a palindrome itself makes this problem very trivial.
• Let us assume that the given string str is a palindrome, so we know that ‘S’ comprises of two halves  ‘S₁’ and ‘S₂’ i.e ‘S’ = ‘S₁' + ‘S₂', where ‘S₁' and ‘S₂’ are two strings, and ‘S₂’ is the reverse of ‘S₁’(in case of odd length palindromes ‘S₂’ won’t have the last character of ‘S₁’). So a change in any of the h...read more

Q2. Rotting Oranges
You have been given a grid containing some oranges. Each cell of this grid has one of the three integers values:
Value 0 - representing an empty cell.
Value 1 - representing a fresh...read more
Ans. Naïve Solution
The idea is very simple and naive. We will process the rotten oranges second by second. Each second, we rot all the fresh oranges that are adjacent to the already rotten oranges. The time by which there are no rotten oranges left to process will be our minimum time.
 
In the first traversal of the grid, we will process all the cells with value 2 (rotten oranges). We will also mark their adjacent cells ...read more

Q2. Merge sort algorithm
Ans. 
Merge sort is a divide and conquer algorithm that divides the input array into two halves, sorts them separately, and then merges them back together in sorted order.
• Divide the input array into two halves

• Recursively sort each half

• Merge the sorted halves back together
