+## reversestrcap
+
+### Instructions
+
+Write a program that takes one or more strings and that, **for each argument**:
+-puts the last character of each word (if it is a letter) in uppercase and the rest
+in lowercase
+-then it displays the result followed by a `\n`.
+
+A word is a sequence of alphanumerical characters.
+
+If there are no parameters, the program displays a `\n`.
+
+Examples of outputs :
+
+```console
