双线macd指标参数最佳设置

Dark is going to attend Motarack’s birthday. Dark decided that the gift he is going to give 双线macd指标参数最佳设置 to Motarack is an array a of n non-negative integers.双线macd指标参数最佳设置

Dark created that array 1000 years ago, so some elements 双线macd指标参数最佳设置 in that array disappeared. Dark knows that Motarack hates to see an array that has two adjacent elements with a high absolute difference between them. He doesn’t have much time so he wants to choose an integer k (0≤k≤109) and replaces all missing elements in the array a with k.

Let m be the maximum absolute difference between all adjacent elements (i.e. the maximum value of |ai−ai+1| for all 1≤i≤n−1) in the array a after Dark replaces all missing elements with k.

Dark should choose an integer k so that m is minimized. Can you help him?双线macd指标参数最佳设置

Input
The input consists of multiple test cases. The first line contains a single integer t (1≤t≤104) — the number of test cases. The description of the test cases follows.

The first line of each test case contains one 双线macd指标参数最佳设置 integer n (2≤n≤105) — the size of the array a.

The second line of each test case contains n integers a1,a2,…,an (−1≤ai≤109). If ai=−1, then the i-th integer is missing. It is guaranteed that at least one integer is missing in every test case.

It is guaranteed, that the sum of n for all test cases does not exceed 4⋅105.

Output
Print the answers for each test case in the following format:

You should print two integers, the minimum possible value of m and an integer k (0≤k≤109) that makes the maximum absolute difference between adjacent elements in the array a equal to m.

Make sure that after replacing all the missing elements with k, the maximum absolute difference between adjacent elements becomes m.

If 双线macd指标参数最佳设置 双线macd指标参数最佳设置 there is more than one possible k, you can print any of them.

Note
In the first test case after replacing all missing elements with 11 the array becomes [11,10,11,12,11]. The absolute difference between any adjacent elements is 1. It is impossible to choose a value of k, such that the absolute difference between any adjacent element will be ≤0. So, the answer is 1.

In the third test case after replacing all missing elements with 6 the array becomes [6,6,9,6,3,6].

|a1−a2|=|6−6|=0;
|a2−a3|=|6−9|=3;
|a3−a4|=|9−6|=3;
|a4−a5|=|6−3|=3;
|a5−a6|=|3−6|=3.
So, the maximum difference between any adjacent 双线macd指标参数最佳设置 elements is 3.

题意:
给你n个数,有些位置得数会丢少,那么该位置就为-1 .问你在丢少的位置上填什么数,可以使得相邻数差得绝对值最小。填完数之后再问你1~n差值最大是多少。

解析:
有三种情况
第一种 : 8,-1,-1,-1
第二种:-1,-1,-1,-1;
第三种 :8,-1,9

虽然说是学习第一个指标,但是其实在上个月我是学过量化,当时第一个学习是均线策略,所以这里指是我在网上开始分享式学习第一个策略。 这里为什么选择EMV作为第一个策略进行学习呢,主要还是觉得相比均线这种只考虑价格指标来说,EMV是兼顾量指标可能更能真实反映市场行情。 为更好地编写代码和理解指标这里复习一下EMV公式:首先EMV是由EM计算出来,短均线和长均线组成。EM = ((当日最高价+当日最低价)/2 - (昨日最高价+昨日最低价)/2)*(当日最高-当日最低)/成交量。 接下来一步

Problem L.Videos

C-bacteria takes charge of two 双线macd指标参数最佳设置 kinds of videos: ’The Collection of Silly Games’ and ’The Collection of Horrible Games’.
For simplicity’s sake, they will be called as videoA and videoB.
There are some people who want to watch videos during today, and they will be happy after watching videos of C-bacteria.
There are n hours a day, m videos are going to be show, and the number of people is K.
Every video has a type(videoA or videoB), a running time, and the degree of happi- ness after someone watching whole of 双线macd指标参数最佳设置 it.
People can watch videos continuous(If one video is running on 2pm to 3pm and another is 3pm to 5pm, people can watch both of them).
But each video 双线macd指标参数最佳设置 only allows one person for watching.
For a single person, it’s better to watch two kinds to videos alternately, or he will lose W happiness.
For example, if the order of video is ’videoA, videoB, videoA, videoB, …’ or ’B, A, B, A, B, …’, he won’t lose happiness; But if the order of video is ’A, B, B, B, A, B, A, A’, he will lose 3W happiness.
Now you have to help people to maximization the sum of the degree of happiness.

Multiple query.
On the first line, there is a positive integer T, which describe the number of data. Next there are T groups of data.
for each group, the first line have four positive integers n, m, K, W : n hours a day, m videos, K people, lose W happiness when watching same 双线macd指标参数最佳设置 videos).
and then, the next m line will describe m videos, four positive integers each line S, T, w, op : video is the begin at S and end at 双线macd指标参数最佳设置 T, the happiness that people can get is w, and op describe it’s tpye(op=0 for videoA and op=1 for videoB).
There is a blank line before each groups of data.
Top=0 or op=1

Your output should include T lines, for each line, output the maximum happiness for the corresponding datum.
