Leetcode 414. 第三大的数 腾讯校招面试题（一次遍历，最大值，次大值，此次大值必须同时更新)

class Solution {
public:
    int thirdMax(vector<int>& nums) {
        long a = LONG_MIN, b = LONG_MIN, c = LONG_MIN;
        for (auto num : nums) {
            if (num > a) {
                c = b;
                b = a;
                a = num;
            } else if (a > num && num > b) {
                c = b;
                b = num;
            } else if (b > num && num > c) {
                c = num;
            }
        }
        return c == LONG_MIN ? a : c;
    }
