+
+Inputs:
+
+A `n × n` grid with `1 >= n >= 9`, and 2 integers `row, col` with `1 <= row, col <= n`, indicating the starting position of the treasure
+hunt.
+
+Clues:
+
+Every cell of the grid contains a number between `11` and <code>n<sup>2</sup></code>. These values provide the coordinates of the
+next cell to search. The treasure is found in a cell whose value matches its location. (The clue says "stay where you are"!) There will
+always be treasure reachable from the starting position.
+
+Output:
+
+The value in the treasure cell reached by following the clues from the starting position.
+
+Example:
+
+Consider the grid below, with starting position <code>row=3,col=4.</code>
+
+```
+34 21 32 44 25
+21 41 43 14 31
+31 45 52 42 23
+33 15 51 44 35
+21 52 33 13 44
+```
+
+Indexes start from 1, so the value in cell <code>3,4</code> is <code>42.</code> Thus the next clue is found in cell <code>4,2.</code> The
+value there is <code>15.</code> Seeking in cell <code>1,5</code> uncovers the clue <code>25,</code> and cell <code>2,5</code>
+contains <code>31.</code> Since the value in cell <code>3,1</code> is <code>31,</code> that is the location of the treasure.

+
+To find the volume (centimeters cubed) of a cuboid you use the formula:
+
+```
+volume = Length * Width * Height
+```
+
+But someone forgot to use proper record keeping, so we only have the volume, and the length of a single side!
+
+It's up to you to find out whether the cuboid has equal sides (= is a cube).
+
+Return `true` if the cuboid could have equal sides, return `false` otherwise.
+
+Return `false` for invalid numbers too (e.g volume or side is less than or equal to 0).
+
+Note: side will be an integer
