46 Interview questions

A Software Engineer was asked 2mo ago
Q. What is Dijkstra's algorithm and how is it applied to graph theory?
Ans. 

Dijkstra's algorithm finds the shortest path between nodes in a graph, optimizing route selection in various applications.

  • Graph Representation: Dijkstra's algorithm works on weighted graphs, where edges have non-negative weights, representing distances or costs.

  • Initialization: It starts by setting the initial node's distance to zero and all others to infinity, marking the initial node as visited.

  • Relaxation Process...

A Software Engineer was asked 10mo ago
Q. Given a string, determine if it is a palindrome, considering only alphanumeric characters and ignoring cases.
Ans. 

A palindrome is a string that reads the same forwards and backwards, like 'racecar' or 'level'.

  • A simple way to check for a palindrome is to reverse the string and compare it to the original.

  • Example: 'madam' reversed is 'madam', so it's a palindrome.

  • Ignoring spaces and punctuation can be important: 'A man, a plan, a canal, Panama!' is a palindrome.

  • Case sensitivity matters: 'Racecar' is not the same as 'racecar' unl...

A Software Engineer was asked
Q. Given a directed acyclic graph (DAG), find a topological ordering of its vertices. Implement the topological sort algorithm.
Ans. 

Topological sort is a linear ordering of vertices in a directed acyclic graph.

  • Topological sort is used to find a linear ordering of vertices in a directed acyclic graph.

  • It is commonly implemented using depth-first search (DFS) algorithm.

  • The algorithm starts by visiting a vertex and then recursively visits all its adjacent vertices before adding it to the result list.

  • Topological sort is not possible if the graph ha...

Q. Given a linked list, reverse the nodes of a linked list k at a time and return its modified list. k is a positive integer and is less than or equal to the length of the linked list. If the number of nodes i...
Ans. 

Reverses a linked list in groups of k

  • Break the linked list into groups of k nodes

  • Reverse each group individually

  • Connect the reversed groups back together

A Software Engineer was asked
Q. Write a program to find the largest palindromic substring in the input string.
Ans. 

Program to find the largest palindromic substring in input string.

  • Iterate through each character in the input string and check for palindromic substrings.

  • Keep track of the largest palindromic substring found so far.

  • Use dynamic programming or expand around center approach for efficient solution.

  • Example: Input string 'babad', largest palindromic substring is 'bab' or 'aba'.

A Software Engineer was asked
Q. Write a program to find all triplets with a given sum.
Ans. 

Program to find all triplets with a given sum in an array.

  • Use three nested loops to iterate through all possible combinations of triplets.

  • Check if the sum of the current triplet is equal to the given sum.

  • Store the triplets that satisfy the condition in a list and return the list.

A Software Engineer was asked
Q. Write a program to find all the elements which are present in one array but not in the other array.
Ans. 

Program to find elements present in one array but not in other array

  • Iterate through each element in the first array and check if it exists in the second array

  • If not found, add it to a new array of unique elements

  • Repeat the process for the second array to find elements unique to it

A Software Engineer was asked
Q. Write a program to evaluate a mathematical expression using stacks.
Ans. 

Program to evaluate a mathematical expression using stack

  • Use a stack to store operands and operators

  • Iterate through the expression and push operands onto the stack

  • When an operator is encountered, pop operands from the stack, perform the operation, and push the result back onto the stack

  • Continue until the entire expression is evaluated

  • The final result will be the top element of the stack

A Software Engineer was asked
Q. Given a set of coin denominations and a target value, find the minimum number of coins required to make the target value using both backtracking and dynamic programming.
Ans. 

Find minimum number of coins for a given value using backtracking and dynamic programming.

  • Backtracking involves exploring all possible solutions and choosing the best one.

  • Dynamic programming involves breaking down the problem into smaller subproblems and solving them.

  • For backtracking, we can start with the largest coin and keep subtracting it until we reach the target value.

  • For dynamic programming, we can create a...
