调整数组顺序使奇数位于偶数前面

题目描述

class Solution {
public:
void reOrderArray(vector<int> &array) {
int len = array.size();
vector<int> v1,v2;
for(int i = 0;i < len ; ++i)
{
if (array[i]%2 == 1)
v1.push_back(array[i]);
else v2.push_back(array[i]);
}
int len1 = v1.size(),len2 = v2.size();
array.clear();
for(int i = 0;i < len1 ; ++i)
array.push_back(v1[i]);
for(int i = 0;i < len2 ; ++i)
array.push_back(v2[i]);
}
};
