Iterate through the matrix and compare each element with its corresponding element in the transpose
If any pair of elements do not match, return false immediately
If all pairs match, return true at the end

I applied via Campus Placement and was interviewed before Jul 2020. There was 1 interview round.
Interview Questionnaire
2 Questions
- Q1. Check if binary tree is balanced or not.
- Ans.
Check if binary tree is balanced or not.
A balanced binary tree has the height of left and right subtrees differ by at most 1.
Recursively check the height of left and right subtrees and compare.
Use a helper function to calculate the height of a subtree.
Time complexity: O(nlogn) for a balanced tree, O(n^2) for a skewed tree.
- Q2. Detect loops in linked list.
- Ans.
Detect loops in a linked list.
Use two pointers, one moving at a faster pace than the other.
If there is a loop, the faster pointer will eventually catch up to the slower one.
To detect the start of the loop, reset one pointer to the head and move both pointers at the same pace.
