/*
	Create a function to simulate change directory(cd) in your terminal, we want to find
	in which folder you end up.
	This function will automate the “$cd” command, so every item in the array is a cd command
	Given a an array of paths where you will use cd path[i], find the result folder
	
	Input:
	paths string[], where paths[i] is a valid path.
	paths[0] = will be your start folder, so it will be a valid path directory.

	example 1:
	paths[] = {"/usr/user_a/home", "..", "desktop", "../.."} -> "/usr"
	explanation:
	cd /usr/user_a/home  -> current path "/usr/user_a/home"
	cd .. -> go up one folder, current path "/usr/user_a/"
	cd desktop -> move to folder desktop, current path "/usr/user_a/desktop"
	cd "../.." -> move two folders up, current path "/usr"
	
	example 2:
	args string[] = {"/usr/user_a/home", "..", "desktop/../../user_b",} -> "/usr/user_b"
	cd /usr/user_a/home  -> current path "/usr/user_a/home"
	cd .. -> go up one folder, current path "/usr/user_a/"
	cd "desktop/../../user_b" -> move to folder desktop, current path "/usr/user_a/desktop", then move two folders up "/usr/", then move to user_b "/usr/user_b"
