WA in EDIST

The solution gives me wrong answer when I allocate memory via malloc but the same solution gets accepted when I declare an array of 2001*2001 globally.
Can someone please explain this ? Thanks

Could be a plethora of things. You could PM me your code and I could explain.

As you noticed, when you defined dp[2001][2001] within main it returned SIGSEGV. This is because memory was exceeded. Read the documentation for malloc.

getting WA in EDIST.....
can u plz suggest me some test cases.....

#include<iostream>
#include<cstring>
using namespace std;
int main()
{
    int n,j,k,m;
    cin>>n;
    int l[n];
   char string1[n][3000];
   char string2[n][3000];
   for(int i=0;i<n;i++)
   {
       cin>>string1[i];
       cin>>string2[i];
       l[i]=0;
   }
   for(int i=0;i<n;i++)
   {
     m=0;
      while(string1[i][m] && string2[i][m])
      {
          if(string1[i][m]!=string2[i][m])
          l[i]++;
          m++;
      }
       k=strlen(string1[i]);
       j=strlen(string2[i]);
        l[i]+=(k>j)?(k-j):(j-k);
        cout<<l[i]<<endl;
   }
}
