Проблем с Pascal Triangle

Здравейте получавам само 66/100 с моето решение. Някой може ли да ми каже как да реша задачата с масиви?

The triangle may be constructed in the following manner: In row 0 (the topmost row), there is a unique nonzero entry 1. Each entry of each subsequent row is constructed by adding the number above and to the left with the number above and to the right, treating blank entries as 0. For example, the initial number in the first (or any other) row is 1 (the sum of 0 and 1), whereas the numbers 1 and 3 in the third row are added to produce the number 4 in the fourth row.

Hints

The input number n will be 1 <= n <= 60
Think about proper type for elements in array
Don’t be scary to use more and more arrays
