Given a string, does "occ" appear in the middle of the string? To define middle, we'll say that the number of characters to the left and right of the "occ" must differ by at most one. Complete the following file: main.cpp 1 #include 2 #include // abs for integers 3 using namespace std; 4 5 bool occMiddle(const string& s) 6 { 7 bool result{false}; 8 string occ = "occ"; 9 10 1/get the length of the string 11 int i = s.length(); 12 if (1 >=3) 13 { 14 for (int i = 0; i
