Create a strconcat function to concatenate two strings into one string. The function will need to call malloc to allocate enough memory to hold the characters from $s1,$ the characters from s$2,$ and the null terminator. After you've allocated the memory, iterate over the $s1$ array to copy it into the new memory that you've allocated. Then, iterate over the $s2$ array and copy that over. Don't forget that the new string should have a null terminator at the end. Finally, the strconcat function will return the pointer to the new string. It is the responsibility of the ma in function to free the memory. Starter code is given below. Don't change the main function.
