# Shuffle~ shuffle~

Consider a string of length $$n$$ where $$n$$ is an positive integer. Also consider some functions or programs that will rearrange the orders of characters of the string given in a certain way according to the program. Note that no function/program can modify the length of the string given (adding or deleting characters) or change its behavior/method of rearranging. Prove or disprove that if a string $$S$$ is being fed into a series of function/program, the result will always be the same regardless of the order of the programs.
