1. You have to find p,q of matrix p*q such that it fill n elements(n given) Such that
a) matrix should be nearest to a square matrix and
b) 0<=((p*q)-n)<=2 2. Zig-zag traversal of tree
3. You are given an array of length k and it have numbers from 0 to n (where k>>>n) in O(n) time and no extra space find occurrences of each element in O(n) time only
1. You are given row and column wise sorted matrix you have to find and delete an element such that it is still sorted in O(n) time.
3. In a BST to every element add sum of elements greater than it.
