C++实现
class Solution

public:
vector<int> findDiagonalOrder(vector<vector<int>>& matrix)
{
if(matrix.empty())
{
return {};
}
vector<int> result;
bool fromUp = false; /* false 自下而上 ture 自上而下*/
int a = 0;
int b = 0; //(a,b) A点
int c = 0;
int d = 0; //(c,d) B点
int endR = matrix.size() - 1;
int endC = matrix[0].size() - 1;
while (a != endR + 1) //a 走到最后一行的时候b到了最后一列
{
this->printLevel(matrix,a,b,c,d,fromUp,result);
a = (b == endC ? a + 1 : a);
b = (b == endC ? b : b + 1);
d = (c == endR ? d + 1 : d);
c = (c == endR ? c : c + 1);
fromUp = !fromUp;
}
return result;
}
private:
/*打印一列*/
void printLevel(vector<vector<int>>& matrix,int a,int b,int c,int d,bool f,vector<int>& result)
{
