Pascal's
Triangle:
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]
]
class Solution {
public:
vector<vector<int> > generate(int n) {
// Start typing your C/C++ solution below
// DO NOT write int main() function
if ( n<=0 )
return vector<vector<int> >();
vector<int> level;
vector<vector<int......
