Given NumRows, generate the first numrows of Pascal ' s triangle.For example, given numrows = 5,Return[ [1], [1,1], [1,2,1], [1,3,3,1], [1,4,6,4,1]]Analysis:
Column j=0 is all 1, column j==i, all 1
Other columns
A[2][1] = a[1][0]+a[1][1]
A[3][1] = a[2][0]+a[2][1]
A[3][2] = a[2][1]+a[2][2]
......
The calculation results
......
A[I][J] = A[i-1][j-1]+a[i-1][j]
