+## generics
+
+### Instructions
+
+Write a functions called identity that calculates the identity of a value (receives any data type and returns the same value)
+
+### Expected Function
+
+```rust
+fn identity(v: _) -> _ {
+}
+```
+
+### Usage
+
+Here is a program to test your function.
+
+```rust
+fn main() {
+	println!("{}", identity("Hello, world!"));
+	println!("{}", identity(3));
+}
+```
+
+And its output
+
+```console
+student@ubuntu:~/[[ROOT]]/test$ cargo run
+Hello, world!
+3
+student@ubuntu:~/[[ROOT]]/test$
+```
