506. Relative Ranks

solution1:使用优先队列;

掌握priority_queuepair的使用;

class Solution {
public:
    vector<string> findRelativeRanks(vector<int>& nums) {
        priority_queue<pair<int, int>> myqueue;//
        for(int i=0; i<nums.size(); i++)
        {
            myqueue.push(pair(nums[i], i));//
        }
        vector<string> ans(nums.size(), "");//
        int idx = 0, cnt = 1;
        for(int i=0; i<nums.size(); i++)
        {
            idx = myqueue.top().second;//
            myqueue.pop();
            if(cnt==1) ans[idx] = "Gold Medal";//
            else if(cnt==2) ans[idx] = "Silver Medal";
            else if(cnt==3) ans[idx] = "Bronze Medal";
            else ans[idx] = to_string(cnt);
            cnt++;
        }
        return ans;

    }
};

solution2: 使用映射map;

【LeetCode】Partition List

Given a linked list and a value x, partition it such that all nodes less than x come before nodes greater than or equal to x. You should preserve the original relative order of the nodes in each of the two partitions. For example,Given 1->4->3->2

【LeetCode】283. Move Zeros

题目 Given an array nums, write a function to move all 0's to the end of it while maintaining the relative order of the non-zero elements. For example, given nums = [0, 1, 0, 3, 12], after calling your function, nums should be [1, 3, 12, 0, 0]. Note:Yo

【leetcode】Generate Parentheses

题目: 给定整数n,返回n对匹配的小括号字符串数组. For example, given n = 3, a solution set is: "((()))", "(()())", "(())()", "()(())", "()()()" 分析: 这种问题的模式是:1)问题的解有多个 ,2)每个解都是由多个有效的 "步骤" 组成的,3)变更以有解的某个或某些"步骤"

【LeetCode】Implement strStr()

Implement strStr() Implement strStr(). Returns a pointer to the first occurrence of needle in haystack, or null if needle is not part of haystack. 标准KMP算法.可参考下文. http://blog.csdn.net/yaochunnian/article/details/7059486 核心思想在于求出模式串前缀与后缀中重复部分,将重复信息保存在n

【LeetCode】Add Two Numbers

You are given two linked lists representing two non-negative numbers. The digits are stored in reverse order and each of their nodes contain a single digit. Add the two numbers and return it as a linked list. Input: (2 -> 4 -> 3) + (5 -> 6 ->

【LeetCode】Pascal&#39;s Triangle

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] ] 这题别想用通项公式做,n choose m里面的连乘必然溢出,老老实实逐层用定义做. class Solution { public: vector<vector<

【LeetCode】Copy List with Random Pointer

A linked list is given such that each node contains an additional random pointer which could point to any node in the list or null. Return a deep copy of the list. 思路:第一遍正常复制链表,同时用哈希表保存链表中原始节点和新节点的对应关系,第二遍遍历链表的时候,再复制随机域. 这是一种典型的空间换时间的做法,n个节点,需要大小为O(n

【leetcode】Max Points on a Line (python)

给定一个点,除该点之外的其他所有点中,与该点的关系要么是共线,要么就是共点,也就是两点重合. 共线有三种情况:水平共线,垂直共线,倾斜的共线.合并下这三种情况就是斜率存在的共线和斜率不存在的共线. 那么我们的任务就是针对每个点,找出与其共线的这些情况中,共线最多的点的个数. 注意:最终的结果别忘了加上共点的个数. class Solution: def maxPoints(self, points ): if len( points ) <= 1: return len( points ) ma

【LeetCode】 Maximum Subarray

Find the contiguous subarray within an array (containing at least one number) which has the largest sum. For example, given the array [−2,1,−3,4,−1,2,1,−5,4], the contiguous subarray [4,−1,2,1] has the largest sum = 6. More practice: If you have figu
