Minimum stepsGiven an array A consisting of positive integers. You have to convert each integer number in the array to some prime number. In each step, you can select any index of the array and decrease or increase the array element present at the selected index by 1. Find the minimum number of steps needed to convert each element of the array to some prime number.Function descriptionComplete the solve function. The function takes the following 2 parameters and returns the minimum number of steps required to convert all array elements to prime numbers:N: Represents the number of elements in the arrayA: Represents the elements of the arrayInput format for custom testingNote: Use this input format if you are testing against custom input or writing code in a language where we don’t provide boilerplate code.The first line contains a single integer N denoting the length of the array.The second line contains N space-separated integers denoting the elements of the array.

Given an integer array A of length N. Where Ai is the cost of stepping on the ith stair.From ith stair, you can go to i+1th or i+2th numbered stair.Initially, you are at 1st stair find the minimum cost to reach Nth stair.Problem Constraints2 <= N <= 1051 <= Ai <= 104Input FormatThe first and only argument is an integer array A.Output FormatReturn an integer.Example InputInput 1:A = [1, 2, 1, 3]Input 2:A = [1, 2, 3, 4]Example OutputOutput 1:5Output 2:7Example ExplanationExplanation 1:1 -> 3 -> 4Explanation 2:1 -> 2 -> 4

You are given two integer arrays: array a𝑎 of length n𝑛 and array b𝑏 of length n+1𝑛+1.You can perform the following operations any number of times in any order:choose any element of the array a𝑎 and increase it by 11;choose any element of the array a𝑎 and decrease it by 11;choose any element of the array a𝑎, copy it and append the copy to the end of the array a𝑎.Your task is to calculate the minimum number of aforementioned operations (possibly zero) required to transform the array a𝑎 into the array b𝑏. It can be shown that under the constraints of the problem, it is always possible.InputThe first line contains a single integer t𝑡 (1≤t≤1041≤𝑡≤104) — the number of test cases.Each test case consists of three lines:the first line contains a single integer n𝑛 (1≤n≤2⋅1051≤𝑛≤2⋅105);the second line contains n𝑛 integers a1,a2,…,an𝑎1,𝑎2,…,𝑎𝑛 (1≤ai≤1091≤𝑎𝑖≤109);the third line contains n+1𝑛+1 integers b1,b2,…,bn+1𝑏1,𝑏2,…,𝑏𝑛+1 (1≤bi≤1091≤𝑏𝑖≤109).Additional constraint on the input: the sum of n𝑛 over all test cases doesn't exceed 2⋅1052⋅105.OutputFor each test case, print a single integer — the minimum number of operations (possibly zero) required to transform the array a𝑎 into the array b𝑏.ExampleinputCopy3121 323 33 3 344 2 1 22 1 5 2 3outputCopy318NoteIn the first example, you can transform a𝑎 into b𝑏 as follows: [2]→[2,2]→[1,2]→[1,3][2]→[2,2]→[1,2]→[1,3].

Geek and Geekina, the top students in their class, were vying for the leadership role. To determine the leader, their teacher assigned them arrays, arr1[] to Geek and arr2[] to Geekina of size n. The task was simple: calculate the cost of each array. The cost of the array is defined as the summing of VAL(a[i]) for each i in [0,n-1].VAL(x)=minimum number of operations to convert x to 0 or 1.In each operation, you can take any prime factor of the remaining value and subtract it from x.For example,  if we have 6, and if we subtract 3 from it, then our remaining value will become 3 and then we can not subtract 2 from it because 2 is not the prime factor of the current value of 3.Due to their busy schedules, Geek and Geekina have sought assistance in calculating the cost of their arrays. So your task is to return  1 if the cost of arr1 is less than or equal to the cost of arr2.  otherwise, it should return 0. Example 1:Input:n=3arr1={1,1,2}arr2={1,1,1}Output:0Explanation:VAL(1) is 0 and VAL(2) is 1 (2->0).Now Cost of arr1 is 1 and Cost of arr2 is 0.So 0 is the answer Cost(arr1)>Cost(arr2).

Egath is participating in a coding hackathon and one of the challenges requires him to work with an array of integers. The task is to remove exactly one element from the array such that the sum of the remaining elements is a prime number. Help Egath find the first possible prime sum by removing one element or determining if no such prime sum can be achieved.Input format :The first line of input consists of an integer N, representing the number of elements in the array.The second line consists of N space-separated integers, representing the array elements.Output format :If removing one element results in a prime sum, print the sum.If no such prime sum can be achieved by removing exactly one element, print "No valid prime sum found".Refer to the sample output for formatting specifications.Code constraints :The given test cases fall under the following constraints:1 ≤ N ≤ 151 ≤ elements of the array ≤ 1000Sample test cases :Input 1 :31 2 3Output 1 :5Input 2 :41 2 4 6Output 2 :11Input 3 :42 3 5 7Output 3 :No valid prime sum found

Write a function:class Solution { public int solution(int[] A); }that, given an array A of N integers, returns the smallest positive integer (greater than 0) that does not occur in A.For example, given A = [1, 3, 6, 4, 1, 2], the function should return 5.Given A = [1, 2, 3], the function should return 4.Given A = [−1, −3], the function should return 1.Write an efficient algorithm for the following assumptions:N is an integer within the range [1..100,000];each element of array A is an integer within the range [−1,000,000..1,000,000].
