SDE

You are given two Singly Linked Lists of integers, which may have an intersection point.

Your task is to return the first intersection node. If there is no intersection, return NULL.

Example:-

The Linked Lists, where a1, a2, c1, c2, c3 is the first linked list and b1, b2, b3, c1, c2, c3 is the second linked list, merging at node c1.

Ninjaland is a country in the shape of a 2-Dimensional grid 'GRID', with 'N' rows and 'M' columns. Each point in the grid has some cost associated with it.

Find a path from top left i.e. (0, 0) to the bottom right i.e. ('N' - 1, 'M' - 1) which minimizes the sum of the cost of all the numbers along the path. You need to tell the minimum sum of that path.

Note:

You can only move down or right at any point in time.
