Data type not able to hold the value while doing DP?

Do you understand the error?

When doing tabulation or memoization, we store the values in a data structure, but if this is not implemented properly we get the wrong result.

Where is the error occurring?

Error could be occurring when we are storing the values in the DP, what are the data types here? Can we check the constraints of the problem?

Why do you think you are seeing this error? What might be causing it?

The values here could exceed the number limit, so some problems require you to mod the values. Can we check the problem statement and see if this is mentioned?

How to Debug this? To debug this issue, I would recommend the following steps

Some of the problems require you to mod the value with 1000000007, this is usually mentioned in the question. Before storing the value in your DP mod it to fix this issue. If this is not done, our number will exceed the int limit and give us a wrong value.
