Normalize File Path

You are given a file path as a string in POSIX style. Your task is to normalize the given file path by:

• Removing the current directory indicators .
• Handling parent directory indicators .. appropriately, by moving up one directory level when possible
• Reducing multiple consecutive slashes (/) to a single slash

Note that if the input path is absolute (i.e. it starts with a slash), the normalized path should also be absolute. If the input path is empty, return "/".

For example, given the path "/a/./b/../../c/" the normalized path is "/c".

inputFormat

The input consists of a single line containing a file path string.

You should read the input from standard input (stdin).

outputFormat

Output a single line containing the normalized file path, printed to standard output (stdout).
