write two functions:
load_treasure_map(filename):
Takes a string as input corresponding to a filename. Opens the treasure map at that filename and loads the treasure map into a list of lists, then returns said list of lists. You can assume that the file will exist. Note that the treasure map could have any number of rows and columns
write_treasure_map(treasure_map, filename):
Takes as inputs a list of lists corresponding to a treasure map and a string corresponding to a filename. Writes the treasure map to a file at the given filename, with a newline after each row of the map. Does not return anything.

Extracted text: In this question, we will go on a hunt for treasure!! We must follow the trail in a treasure map, which has been split across multiple files. Along with this PDF we provide you three examples of treasure map files: map0.txt, map1.txt and map8.txt. Here is the contents of one such treasure map file, map8.txt: >>v......V ^v^. You will observe that there is what could be considered a 'trail' in the file. A trail, which in this case starts in the top-left corner, can be composed of the following characters: '>', '<', 'v'="" and="" '^'.="" you="" must="" follow="" this="" trail="" (by="" looking="" at="" the="" character="" to="" the="" right,="" left,="" below="" or="" above,="" respectively),="" until="" you="" reach="" a="" .'="" character="" at="" the="" end.="" you="" will="" then="" place="" an="" 'x'="" at="" said="" location="" to="" mark="" that="" you="" have="" found="" the="" location="" of="" the="" treasure,="" and="" save="" a="" new="" file="" containing="" the="" updated="" treasure="" map.="" e.g.,="" for="" the="" file="" above,="" after="" following="" the="" trail,="" you="" would="" create="" a="" new="" file="" called="" new_map8.txt="" containing="" the="" following:="">>v. ..v...... V ..>>>>X.. .^v^ You will also observe that there can be other trails in the file, leading perhaps to dead-ends or even off the grid. These false trails must be ignored. There are other special characters that can appear in a file. For example, here is the file map0.txt provided to you with this PDF: >>>v...... ...v... v..v. v..>>* You will observe that there is a trail beginning in the upper-left corner and ending at row 4, column 5, where there is a '*' character. This character is a 'fall-through' character. It means that you should continue the trail at the same row and column (row 4, column 5) of the next map file. Since this is mapo.txt, you must thus check in map1.txt and start looking at the trail at row 4, column 5 (instead of the top-left corner). Similarly, the '|' character is a ladder character: if you encounter this character in a particular row and column position, then you must look into the preceding map file and start the trail at that same row and column position.
