Sfida di programmazione: Reverse a String

Problema

Reverse text so the last character comes first.

Implement reverse_string(text).

text: The text to reverse.

Return the reversed text.

0 ≤ length ≤ 10,000

Esempio 1

Input:
text = "hello"

Output atteso:
expected = "olleh"

Input:
std::string text = "hello";

Output atteso:
std::string expected = "olleh";

Input:
string text = "hello";

Output atteso:
string expected = "olleh";

h-e-l-l-o read backwards is "olleh".

Esempio 2

Input:
text = "a"

Output atteso:
expected = "a"

Input:
std::string text = "a";

Output atteso:
std::string expected = "a";

Input:
string text = "a";

Output atteso:
string expected = "a";

A single character reversed is itself.
