Coding Round

In this Round there were 6 sets questions.

Each set of question paper were include 3 coding questions. (Basically from LeetCode Basic – medium level)

Some of the questions that I remember are:

1. Given an array of numbers from which we have to return the 2nd largest number from the array. Also, there were some test cases like if there is only one number in the array then return -1 .
2. Write a function to reverse a string using a recursive approach/ recursive function.
3. Given a string s containing just the characters ‘(‘, ‘)’, ‘{‘, ‘}’, ‘[‘ and ‘]’, determine if the input string is valid.

An input string is valid if:

1. Open brackets must be closed by the same type of brackets.
2. Open brackets must be closed in the correct order.
3. Every close bracket has a corresponding open bracket of the same type.

Valid Parentheses

Example 1:

Input: s = "([){]}([[]])"
Output: Balanced

4. Given an array of nums of distinct integers, return all the possible permutations. You can return the answer in any order.

Example 1:

Input: nums = [1,2,3]
Output: [[1,2,3],[1,3,2],[2,1,3],[2,3,1],[3,1,2],[3,2,1]]
