Correct answer will be upvoted else downvoted. Computer science.
You are given two integers n and k.
You ought to make a variety of n positive integers a1,a2,… ,a to such an extent that the total (a1+a2+⋯+an) is distinguishable by k and greatest component in an is least conceivable.
What is the base conceivable most extreme component in a?
Input
The primary line contains a solitary integer t (1≤t≤1000) — the number of experiments.
The solitary line of each experiment contains two integers n and k (1≤n≤109; 1≤k≤109).
Output
For each experiment, print one integer — the base conceivable most extreme component in cluster a to such an extent that the aggregate (a1+⋯+an) is distinct by k.
Correct answer will be upvoted else downvoted. Computer science.
Positive integer x is called divisor of positive integer y, in case y is distinguishable by x without remaining portion. For instance, 1 is a divisor of 7 and 3 isn't divisor of 8.
We gave you an integer d and requested that you track down the littlest positive integer a, to such an extent that
a has no less than 4 divisors;
contrast between any two divisors of an is essentially d.
Input
The primary line contains a solitary integer t (1≤t≤3000) — the number of experiments.
The primary line of each experiment contains a solitary integer d (1≤d≤10000).
Output
For each experiment print one integer a — the response for this experiment.
Prove that the next issue is in the NP class:
An integer t and a collection of integers S have been provided to us. Is there a subset of S whose elements add up to t?

- Correct answer will be upvoted else Multiple Downvoted. Computer science. You are given an arrangement an of length n comprising of integers from 1 to n. The grouping may contain duplicates (for example a few components can be equal). Track down the number of tuples of m=3 components with the end goal that the maximum number in the tuple varies from the base by close to k=2. Formally, you want to view as the number of triples of lists i<j<z with the end goal that max(ai,aj,az)−min(ai,aj,az)≤2. For example, on the off chance that n=4 and a=[1,2,4,3], there are two such triples (i=1,j=2,z=4 and i=2,j=3,z=4). In the event that n=4 and a=[1,1,1,1], all four potential triples are suitable. Input The principal line contains a solitary integer t (1≤t≤2⋅105) — the number of experiments. Then, at that point, t experiments follow.

Officially, there are n members, the I-th member picked the number man-made intelligence. The victor of the game is such a member that the number he picked is novel (I. e. no other individual picked this number aside from him) and is insignificant (I. e. among all exceptional upsides of a the base one is the triumphant one). Your undertaking is to find the record of the member who dominated the match (or - 1 in case there is no victor). Ordering is 1-based, I. e. the members are numbered from 1 to n. You need to answer t autonomous experiments. Input The primary line of the input contains one integer t (1≤t≤2⋅104) — the number of experiments. Then, at that point, t experiments follow.
