Problem
Build a new string from the characters of text at positions 0, 2, 4, … (every other character, starting with the first).
Implement every_other_character(text).
Input
text: The original text.
Output
Return the characters at even positions, in order.
Constraints
0 ≤ length of text ≤ 10,000
Examples
Example 1
Input:
text = "programming"
Expected output:
expected = "pormig"Input:
std::string text = "programming";
Expected output:
std::string expected = "pormig";Input:
string text = "programming";
Expected output:
string expected = "pormig";Explanation
Positions 0, 2, 4, 6, 8, 10 give p, o, r, m, i, g: "pormig".
Example 2
Input:
text = "a"
Expected output:
expected = "a"Input:
std::string text = "a";
Expected output:
std::string expected = "a";Input:
string text = "a";
Expected output:
string expected = "a";Explanation
Only position 0 exists: "a".
