Sample Nokia interview questions

1
Merge Overlapping Intervals Merge overlapping intervals in an array. Input: intervals = [[1,4],[4,5]] Output: [[1,5]] Explanation: The intervals touch exactly at the 4 mark, so they are successfully merged into a single continuous interval.

2
Dot Product of Two Sparse Vectors Calculate the dot product of two sparse vectors. Input: nums1 = [0,1,0,0,2], nums2 = [0,0,0,0,5] Output: 10 Explanation: Multiplies the aligned non-zero values (2 * 5) and ignores all the zeros, yielding a dot product of 10.
codingmedium
3
Vertical Order Traversal Perform a vertical order traversal of a binary tree. Input: root = [1,2,3,4,5,6,7] Output: [[4],[2],[1,5,6],[3],[7]] Explanation: Traverses the tree maintaining column indices, seamlessly grouping nodes that share the exact same vertical alignment.
codingmedium
4
Continuous Subarrays Sum Equals K Find the total number of continuous subarrays whose sum equals K. Input: nums = [1,2,3], k = 3 Output: 2 Explanation: Both the contiguous subarray [1,2] and the single-element subarray [3] sum perfectly to the target of 3.
codingmedium
5
Iterator over a Binary Search Tree Implement an iterator over a binary search tree. Input: root = [7,3,15,null,null,9,20], calls: next(), hasNext(), next() Output: 3, TRUE, 7 Explanation: The iterator yields the smallest value (3), confirms more nodes exist, then properly yields the next in-order value (7).
