Hi Is it wrong?
If not why is there an error in the last line?
error:Index was outside the bounds of the array.

C#

const int n = 5;
        int[,] next=new int[n,n];

            for(int i=0;i<=n;i++)
                for (int j = 0; j <= n; j++)
                    next[i,j]= -1;

Solution 2

You are creating a two dimensional array, with the first dimension holding an array of 5 integers, but if you use i = 0; i <= 5 you actually create 6 integers (starts with 0), and so basically, you are trying to fit 6 integers into an array that was declared to hold only 5. Either declare n = 6, or use i = 0; i < 5 in your loops. Hope this helps.

Solution 1

I think

C#

for(int i=0;i<=n;i++)
                for (int j = 0; j <= n; j++)

will be

C#

for(int i=0;i<n;i++)
                for (int j = 0; j < n; j++)

For 0 to 5 means its taking value for 6 times .But array is declared with max size of 5.
