The coding round consisted of 3 coding questions. 1st question was of 20 marks, 2nd and 3rd of 50 marks.

Q1. Minimum Number Of Operations
You are given an array 'ARR' of 'N' positive integers. You need to find the minimum number of operations needed to make all elements of the array equal. You can...read more
Ans. Brute Force
For making all elements equal you can select a target value and then you can make all elements equal to that. Now, for converting a single element to a target value you can perform a single operation only once. In this manner, you can achieve your task in the maximum of  ‘N’ operations but you have to minimize this number of operations and for this, your selection of target is very important because if ...read more

Q2. Avoiding Traps
Given an array of 'N' elements 'OBSTACLES', where each element represents the coordinate of the obstacle on a straight line. We start jumping from point 0 and we need to reac...read more
Ans. 
I first made an array in the main function that will contain the number of prime numbers less than or equal to the index value of the array and passed into my called function. This will give me the a value for each test case. Then, int the called function I applied dynamic programming. I created a dp array and initialized all values to max integer (dp[0] = 0). For each index i, i put dp[i+1] if (i=(r1/r2)) equal to min...read more

Q3. Longest Consecutive Sequence
You are given an unsorted array/list 'ARR' of 'N' integers. Your task is to return the length of the longest consecutive sequence.
The consecutive sequence ...read more
Ans. Brute Force
As we only need the consecutive elements in the form ['NUM', 'NUM' + 1, 'NUM' + 2,...,'NUM' + 'L']. The brute force approach is to traverse each element in the array ('NUM' = ‘ARR[i]’) and then keep finding ('NUM' + 1) in the array until we don't find the next consecutive element in the array.
 
Keep a track of the current length of the sequence. If the current length of the consecutive subsequence is gre...read more

For example:
 If the given string is: STR =...read more
Ans. 
He asked me to write a function to reverse a string of size n. In this question I defined my string ans="" , then iterated i from n-1 to 0 and concatenated Character.toString(s.charAt(i)) to my ans and then returned ans. He followed up the question. He said “If I remove ' ”="" ' in string ans line then what will happen. I answered that it will give me a compilation error that the variable "ans" is not initialized. Then...read more

Q3. Balanced parenthesis program
Add your answer
Q4. Explain your approach to solving balanced parenthesis program
Ans. 
I approach solving balanced parenthesis program by using a stack data structure.
• Use a stack to keep track of opening parentheses

• Iterate through the input string and push opening parentheses onto the stack

• When a closing parenthesis is encountered, pop from the stack and check if it matches the closing parenthesis

• If stack is empty at the end and all parentheses are matched, the string is balanced
