Max Function

Statistical function is of many categories. One of them is a MAX function. The MAX function returns the largest value from the list of arguments passed to it. MAX function always ignores the empty cells when performing the calculation.

Power Function

A power function is a type of single-term function. Its definition states that it is a variable containing a base value raised to a constant value acting as an exponent. This variable may also have a coefficient. For instance, the area of a circle can be given as:

Question

Please answer 2 python questions. Thank you.

A variable is...
O A value that we can never be certain of the value of before we check it
A named "box" in memory that holds the value of something
Text like "hello" or "enter a number"
O A number like 30 or 300

We can use strings for...
O Text values that we don't want otherwise interpreted
O Numerical values
O Fuzzy values that have no specific definition
O Logical values like "yes" and "no"

Correct answer will be upvoted else downvoted. Computer science. Presently Nezzar has a beatmap of n particular focuses A1,A2,… ,An. Nezzar might want to reorder these n focuses so the subsequent beatmap is great. Officially, you are needed to find a change p1,p2,… ,pn of integers from 1 to n, to such an extent that beatmap Ap1,Ap2,… ,Apn is great. In case it is unthinkable, you ought to decide it. Input The primary line contains a solitary integer n (3≤n≤5000). Then, at that point, n lines follow, I-th of them contains two integers xi, yi (−109≤xi,yi≤109) — directions of point Ai. It is ensured that all focuses are unmistakable. Output In case there is no arrangement, print −1. In any case, print n integers, addressing a legitimate change p. In case there are numerous potential replies, you can print any.
A very known application in natural language processing is to extract information from a given text. In this lab, you will be able to extract some emotions (Sad and Happy) from a given string and calculate the score of each emotion. You will be given below the words that express sadness, anger, and happiness. For each word, you will be given weight as well, so that when you are calculating for example the score for sadness in the text (string), you can use this formula:
Correct answer will be upvoted else Multiple Downvoted. Don't submit random answer. Computer science. A string b is an aftereffect of a string an if b can be gotten from a by cancellation of a few (conceivably, zero or all) characters. For instance, "xy" is an aftereffect of "xzyw" and "xy", yet not You are given a string a. Your errand is to reorder the characters of a so that "trygub" isn't an aftereffect of the subsequent string All in all, you should find a string b which is a stage of images of the string an and "trygub" isn't an aftereffect of b We have a genuinely superb confirmation that any string can be sorted out not to contain "trygub" as an aftereffect, however this issue explanation is too short to even think about containing it Inpu The primary line contains a solitary integer t (1≤t≤100) — the number of experiments The primary line of each experiment contains a solitary integer n (1≤n≤200) — the length of a The following line contains the string an of…
