MAQ Software Software Developer Interview Questions and Answers
21 Interview questions
Count the occurrence of each element in an array of strings
Iterate through the array and use a hashmap to store the count of each element
If element already exists in the hashmap, increment its count by 1
Return the hashmap with element counts
Sort an array of strings containing '0', '1', and '2'.
Use counting sort algorithm to count the occurrences of '0', '1', and '2'.
Create a new array with the sorted counts of '0', '1', and '2'.
Join the sorted array back into a single array of strings.
Sort a vector based on another vector
Use std::sort with a custom comparator function
The comparator function should compare the indices of the elements in the second vector
The first vector should be sorted based on the order of the indices in the second vector
Process a string based on specific instructions to manipulate its content effectively.
Identify the instructions: Understand what operations need to be performed on the string.
Use string methods: Utilize built-in functions like split(), join(), replace(), etc.
Consider edge cases: Handle empty strings, special characters, and whitespace appropriately.
Example: For instruction 'reverse', apply string slicing: str[::-1...
Reverse Words in a String: Problem Statement
You are given a string of length N. Your task is to reverse the string word by word. The input may contain multiple spaces between words and may have leading or...
Reverse words in a string while handling leading, trailing, and multiple spaces.
Split the input string by spaces to get individual words
Reverse the order of the words
Join the reversed words with a single space in between
Circular Linked List Detection
You are provided with the head of a linked list containing integers. Your task is to determine if the linked list is circular.
Note:
- A linked list is considered circular...
Detect if a given linked list is circular by checking if it forms a closed loop.
Traverse the linked list using two pointers, one moving at double the speed of the other.
If the two pointers meet at any point, the linked list is circular.
If the faster pointer reaches the end of the list (NULL), the linked list is not circular.
Sort 0 1 2 Problem Statement
Given an integer array arr of size 'N' containing only 0s, 1s, and 2s, write an algorithm to sort the array.
Input:
The first line contains an integer 'T' representing the nu...Sort an array of 0s, 1s, and 2s in linear time complexity.
Use three pointers to keep track of 0s, 1s, and 2s while traversing the array.
Swap elements based on the values encountered to sort the array in-place.
Time complexity should be O(N) and space complexity should be O(1).
N Queens Problem
Given an integer N, find all possible placements of N queens on an N x N chessboard such that no two queens threaten each other.
Explanation:
A queen can attack another queen if they are...
The N Queens Problem involves finding all possible placements of N queens on an N x N chessboard without threatening each other.
Use backtracking algorithm to explore all possible configurations.
Keep track of rows, columns, and diagonals to ensure queens do not threaten each other.
Generate all valid configurations and print them out.
Pair Sum Problem Statement
You are given an integer array 'ARR' of size 'N' and an integer 'S'. Your task is to find and return a list of all pairs of elements where each sum of a pair equals 'S'.
Note:
...
Find pairs of elements in an array that sum up to a given value, sorted in a specific order.
Iterate through the array and for each element, check if the complement (S - current element) exists in a hash set.
Keep track of pairs in a hash set to avoid duplicates.
Sort the pairs based on the criteria mentioned in the question.
Return the sorted list of pairs.
Buy and Sell Stock Problem Statement
Imagine you are Harshad Mehta's friend, and you have been given the stock prices of a particular company for the next 'N' days. You can perform up to two buy-and-sell t...
The task is to determine the maximum profit that can be achieved by performing up to two buy-and-sell transactions on a given set of stock prices.
Iterate through the array of stock prices and calculate the maximum profit that can be achieved by buying and selling at different points.
Keep track of the maximum profit after the first transaction and the maximum profit overall by considering different combinations of ...

- Q1. Find the first occurrence of an element in an rotated array.
- Ans.
Find the first occurrence of an element in a rotated sorted array efficiently using binary search.
A rotated array is a sorted array that has been rotated at some pivot. Example: [4, 5, 6, 7, 0, 1, 2] is a rotated version of [0, 1, 2, 4, 5, 6, 7].
To find the first occurrence, use binary search to reduce time complexity to O(log n).
Check the middle element; if it matches the target, continue searching in the left half to...
