/* You are given an array of strings. The jumper can be anywhere in the array and is denoted by the 'o' symbol.
 * You need to determine the movement of the jumper in iterations. On each iteration the jumper moves
 * one line down, pulled by gravity. Additionally, the jumper moves sideways by the wind on the current line.
 * The '>' symbol means the wind is moving the jumper one position to the right.
 * The '<' symbol means the wind is moving the jumper one position to the left.
 * The total direction of the wind on a single line may stack (e.g. '>>>' moves the jumper 3 positions to
 * the right; '><<' moves the jumper 1 position to the left).
 * The jumper will never fly off the map!
 * The jumper can move only through 'air' (the '-' symbol). When the jumper hits the ground, water or a cliff,
 * the jump is finished!
 * Your task is to determine how the jumper will finish his jump and where he will land exactly, based on
 * the gravity and wind parameters!
 * The symbols in input strings will not separated by anything!
 * The output should consist of two lines. On the first line you must display 1 of 3 possible messages:
 * If you have landed on the ground ('_' symbol), the message is: "Landed on the ground like a boss!";
 *If you have landed in the water ('~' symbol), the message is: "Drowned in the water like a cat!";
 *If you have landed on a cliff ('/', '\' or '|' symbol), the message is: "Got smacked on the rock like a dog!".
 *The second line holds the position (the row and col, space-separated) of your landing. */
