In this question we get a string str, and an array of n chars: c[0...n-1]. The function returns an array of n strings consisting of the str concatenated with c[0], c[1]... c[n-1]. The returned array and the strings in it must all be dynamically allocated. char** append_chars (const char* str, int n, char* chars); For example append_chars ("abc", 3, ['x', 'y', 'c']) needs to return the array ["abcx", "abcy", "abcc"]. • append_chars(", 4, ['x', 'y', 'z', 'x']) needs to return the array ["x", "y", "z", "x"].

In this question we get a string str, and an array of n chars: c[0...n-1]. The function returns an
array of n strings consisting of the str concatenated with c[0], c[1]... c[n-1].
The returned array and the strings in it must all be dynamically allocated.
char** append_chars (const char* str, int n, char* chars);
For example
append_chars("abc", 3, ['x','y','c']) needs to return the array
["abcx", "abcy", "abcc"].
append_chars(", 4, ['x','y','z 'x']) needs to return the array
["x", "y", "z", "x"].
