The algorithm is designed and the code is written out to remove the repeated characters in the string, and no additional cache space is used.Note: The ability to use an additional one or two variables, but does not agree to open an additional array

Each recursive call copies the process (precisely, "variable") in memory. Once a process has ended (some data will be returned), the copy of the process in memory is discarded. Recursion can seem simple, but visualizing the execution of a trace
