need help with this c++ for loop problem

/** * * * * Problem 1: Simple strings & loops Given a string and an int n, create a new string made of the first n characters of the original string, followed by the first n-1 characters of the original string, and so on. You may assume that n is between 0 and the length of the string, inclusive (i.e. n >= 0 and n <= str.length()) } Some examples: "Chocolate", "Chocolate", 4 -> "ChocChoChC" 3 -> "ChoChC" "Ice Cream", 2 -> "IcI" */ string decreasing (const string& str, int n) { string result = "not done"; // Add your code here for() return result;
