i can't figure out why my solution getting WA.

am using greedy approach and it passed many cases.

there's any cases fail my code ?


#include <iostream>
#include <string>
#include <vector>
#include <algorithm>
#include <string.h>
using namespace std;
void Simplify(string &Exp)
{
bool neg[100000 ...

what data type should be used in this problem ??
