INTRO TO ONE OF THE CHALLENGES

This challenge is called Diamond Mine. It is your new favourite game.

Its map is represented as a square matrix. The board is filled with cells, and each cell will have an initial value as follows:

  • A value ≥ 0 represents a path.
  • A value of 1 represents a diamond.
  • A value of −1 represents an obstruction.

The basic rules for playing Diamond Mine are as follows:

  • The player starts at (0, 0) and moves to (n−1, n−1), by moving right (→) or down (↓) through valid path cells.
  • After reaching (n−1, n−1), the player must travel back to (0, 0) by moving left (←) or up (↑) through valid path cells.
  • When passing through a path cell containing a diamond, the diamond is picked up. Once picked up, the cell becomes an empty path cell.
  • If there is no valid path between (0, 0) and (n−1, n−1), then no diamonds can be collected.
  • The ultimate goal is to collect as many diamonds as you can.

This computing challenge that can be solved in a great number of coding languages, but most developers so far solved it successfully by choosing these languages they knew best: C++, C, C++14, Java 8, Python 3, Java 7, Python 2, JavaScript (Node.js), PHP, Kotlin, PyPy3, R, Swift, Go, Objective-C
