Curie’s Waterfall

Input

Two integers representing the number of rows and columns of the waterfall wall, followed by a series of waterfall elements, which ends with an "end" string. Each element is represented by a different character, followed by the position of the element, represented by a row and a column. Each of the elements is defined as follows: - Font: the character ’O’. - Rock: the character ’R’. - Wormhole: the character ’W’ (followed by 2 connected positions). - Black hole: the character ’B’. - Magnet: the character ’M’ followed by its position, the type of magnet (- for repulsion and + for attraction), the radius of the magnetic field, and its power (both integer). All the given numbers are integers.

Output

A two-dimensional diagram of the waterfall, representing the path (or paths) the radioactive fluid will follow, according to the input configuration of Curie’s Waterfall. Each cell is represented by a character, with an empty space represented by a dot (’.’), and the rest of the characters as outlined in the instructions. The path of the fluid should be represented by the character ’O’.
