Problem 55980. Generate Pascal's Triangle Matrix

Difficulty:
(2)
Rate
Pascal's triangle is an arrangement of numbers where each value is the sum of the values adjacent to it in the previous row:
The values can also be calculated directly. The value of the row is . For example, the fifth row is 1, 4, 6, 4, 1:
nchoosek(4,0)
ans =
1
nchoosek(4,1)
ans =
4
nchoosek(4,2)
ans =
6
nchoosek(4,3)
ans =
4
nchoosek(4,4)
ans =
1
Given a positive integer n, return an n-by-n matrix that represents the values of the first n rows of Pascal's triangle. The first k values of the kth row of the matrix will be the values from Pascal's triangle; the remaining n-k values should be 0.
For example, for n = 6, the output should be
1 0 0 0 0 0
1 1 0 0 0 0
1 2 1 0 0 0
1 3 3 1 0 0
1 4 6 4 1 0
1 5 10 10 5 1
