TopicGiven numrows, generate the first numrows of Pascal ' s triangle.For example, given numrows = 5,Return[ 1], [ 1,2,1], [ 1,3,3,1], [ 1,4,6,4,1][Topic Analysis] Pascal Triangle, also known as Yang Hui Triangle, to a number of rows, output Yang Hui triangle, need to combine the nature of Yang Hui Triangle. We produce results mainly on the basis of this nature: each number equals the sum of the t

VC Inside: Pascal==callback==winapi==__stdcall _stdcall is the default invocation of the PASCAL program, usually used in the Win32 API, the function uses a right-to-left stack, and then empties itself at the exit. After the VC compiles the function, it adds an underscore prefix to the function name, followed by the function name with the "@" and the number of bytes of the parameter. _cdecl are the default

Note:Calculates the number of rows starting from 0, that is, 0th actions [1] Example: Input: k = 3 Output: [1, 3, 3] [[1], [], [, 1], [,], [, 1]Solutions Now we need to consider saving space on the basis of Pascal's Triangle. We can know that row k requires (k + 1) space, a
