Nine degree topic 1006:zoj problem

Learned the theory of computing, looking back at this problem is more handy a lot.

The number of O in the ' Z ' is ' a ', ' Z ' and ' j ' between B, ' J ' and the number of O is C.

Analytic grammars can be found that the strings that match the grammar will meet:

1) b!= 0

2) A * b = c


Code:

#include <iostream>
#include <string>

using namespace std;

int main ()
{
	string str;

	while (Cin >> str)
	{
		int z_index=-1, j_index=-1;
		BOOL More_than_one_z_or_j = false;
		for (size_t i = 0; i < str.size (); + + i)
		{
			if (str[i]== ' z ' && z_index==-1)
			{
				Z_index = i;
  } else if (str[i]== ' J ' && J_index==-1)
			{
				j_index = i;
			} else if (Str[i]!= ' o ')
			{
				mor E_than_one_z_or_j = true;
				break;
			}
		}
		if (More_than_one_z_or_j = = False
			&& z_index!=-1
			&& j_index!=-1
			&& Z_index + 1 < J_index
			&& z_index* (j_index-z_index-1) = = (Str.size () -1-j_index))
		{
			cout << " Accepted "<< Endl;
		} else
		{
			cout << "wrong Answer" << Endl;
		}
	}

	return 0;
}
