You must solve N problems with the numbers 1..N. The problems are listed in order of increasing complexity, with the ith problem having an estimated difficulty level of i. Each issue has also been given a grade of vi by you. Comparable vi values lead to similar types of issues. You will pick a portion of the issues and address them each day. You've made the decision that each issue you solve on that day should be more difficult than the one before it. It will also be less monotonous if the vi ratings of the subsequent problems you answer differ by at least K. What is the shortest amount of time that you can fix every issue?Input FormatThe first line contains the number of test cases T. T test cases follow. Each case contains an integer N and K on the first line, followed by integers v1,...,vn on the second line.Constraints1 <= T <= 1001 <= N <= 3001 <= vi <= 10001 <= K <= 1000Output FormatOutput T lines, one for each test case, containing the minimum number of…

Suppose you have to select one project partner from a set of four classmates, who have different GPAs. Assume you do not know any student’s GPA in advance but can get to know it after you have picked a student from that group (a) Suppose you pick one of the four students at random and accept that student as your project partner. What is the probability that your partner is the one with the highest GPA? (b) Suppose you decide to reject the first student and to then accept the next student if and only if that student has a higher GPA. Note that you MUST have a partner, so if the first three are rejected by you, then you have to accept the fourth student. What is the probability that your partner will be the one with the highest GPA.
Artificial intelligence. In a study about the effect of different doses of a medicament, one patient got 2 mg and took 5 days to cure, 2 patients got 3.2 mg and took 8 days to cure, another patient got 4 mg and took 10 days to cure. A patient has taken 6 days to cure, what is the dose he/she received? Tip: use a regression analysis Please answer the question using a equation with detail explanation. Thank you
Alert: Don't submit AI generated answer and propvide detail solution with proper explanation and step by step answer. prove by cases that : | x+ y| <= |x| + |y|
