+
+### Instructions
+
+Write a program that:
+
+- first prints the Latin alphabet alternatively in lowercase and uppercase in reverse order (from `'z'` to `'A'`) on a single line.
+- second prints the Latin alphabet alternatively in lowercase and uppercase in order (from `'a'` to `'Z'`) on a single line.
+
+A line is a sequence of characters preceding the [end of line](https://en.wikipedia.org/wiki/Newline) character (`'\n'`).
+
+Please note that `casting` is not allowed for this exercise!
