代码整理一下：

#include<bits/stdc++.h>
using namespace std;
int w[15][15];
bool check(int xa, int ya, int xb, int yb) {
    int a[2] = {0, 0};
    for (int i = xa; i <= xb; i++) {
        for (int j = ya; j <= yb; j++)
            a[w[i][j]]++;
    }
    return a[0] == a[1];
}
int main()
{
    int n,m;
    cin>>n>>m;
    string a;
    for(int i=1;i<=n;i++)
    {
        cin>>a;
        for(int j=1;j<=a.size();j++)
        {
            if(a[j]=='1')
            {
                w[i][j]==1;
            }
            else
            {
                w[i][j]==0;
            }
        }
    }
    int ans = 0;
    for (int i = 1; i <= n; i++) {
        for (int j = 1; j <= m; j++) {
            for (int ii = i; ii <= n; ii++) {
                for (int jj = j; jj <= m; jj++) {
                    if (check(i, j, ii, jj))
                        ans = max(ans, (ii - i + 1) * (jj - j + 1));
                }
            }
        }
    }
    cout << ans << endl;
    return 0;
}
