Coding problem1
It was an online MCQ's + coding round consisting of 20 MCQ’s and 1 coding problem.
1. Detect and Remove Loop
Moderate
10m average time
90% success
0/80
Asked in companies
Given a singly linked list, you have to detect the loop and remove the loop from the linked list, if present. You have to make changes in the given linked list itself and return the updated linked list.
Expected Complexity: Try doing it in O(n) time complexity and O(1) space complexity. Here, n is the number of nodes in the linked list.
Problem approach
I used two pointer approach (fast and slow). Put slow to head and fast to next of head.Slow was moving one by one and fast was covering 2 nodes at a time and if both the pointers meet at some point then there is a loop in linked list.

9. Puzzle question:Climbing Ant Interview Puzzle
10.1 Coding question: Rotate 2d array
1. Puzzle
An ant climbs 6 meters and falls 3 meters in the alternate minutes. How much time will the ant take to climb a wall that is 60 meters high
Problem approach
Tip 1 : The ant climbs 6 meters in one minute and then falls down 3 meters in the second minute, the distance that it covers in 2 minutes is 3 meters.
Thus for climbing 54 meters, the ant will require time = 52*2/3 = 36 minutes.
We have counted only for 54 meters as it will climb the remaining six meters in one minute.
Thus the total time required to climb the 60 meters wall = 36 + 1 = 37 minutes.
2. Inplace rotate matrix 90 degree
Easy
12m average time
80% success
0/40
Asked in companies
You are given a square matrix of non-negative integers of size 'N x N'. Your task is to rotate that array by 90 degrees in an anti-clockwise direction without using any extra space.
For example:
For given 2D array :
[ [ 1, 2, 3 ],
[ 4, 5, 6 ],
[ 7, 8, 9 ] ]
After 90 degree rotation in anti clockwise direction, it will become:
[ [ 3, 6, 9 ],
[ 2, 5, 8 ],
[ 1, 4, 7 ] ]
Problem approach
i) find the transpose of matrix, which can be done in O(n) easily
ii) reverse the transpose
