leetcode 除自身以外数组的乘积 中等

 直接看代码，比文字解释清楚

class Solution {
public:
    vector<int> productExceptSelf(vector<int>& nums) {
        vector<int> res(nums.size(), 1);
        int lef = 1, rig = 1;
        for(int i = 0, j = nums.size() - 1; i < nums.size(); ++ i, --j) {
            res[i] *= lef;
            res[j] *= rig;
            lef *= nums[i];
            rig *= nums[j];
        }
        return res;
    }
};
