How to update the Go version

System: Debian/Ubuntu/Fedora. Might work for others as well.

1. Uninstall the exisiting version

As mentioned here, to update a go version you will first need to uninstall the original version.

To uninstall, delete the /usr/local/go directory by:

    def longestIncreasingPath(self, matrix: List[List[int]]) -> int:
        '''
        return the length of longest increasing path and its path node
        '''
        if len(matrix) == 0: return 0
        self.memo = [[-1 ] *len(matrix[0]) for j in range(len(matrix))]
        self.path_memo = [[None] *len(matrix[0]) for j in range(len(matrix))]
        max_path = 0
