Problem StatementRajini is a student who loves coding. He is working on an array operations problem. In the given problem, Rajini needs to remove the first element from the array and print the modified array.Help Rajini write a program that takes an array of integers as input, deletes the first element from the array, and prints the modified array.Input format :The first line of input is an integer n, representing the number of elements in the array.The second line of input consists of n space-separated integers, representing the elements of the array arr[i].Output format :The output displays n space-separated integers of the modified array after deleting the first element.Refer to the sample output for the formatting specifications.Code constraints :In this scenario, the test cases will fall under the following constraints:2 ≤ n ≤ 101 ≤ arr[i] ≤ 100Sample test cases :Input 1 :56 7 4 3 1Output 1 :7 4 3 1 Input 2 :210 47Output 2 :47 Input 3 :1037 84 27 23 48 19 1 38 27 39 100Output 3 :84 27 23 48 19 1 38 27 39

Single File Programming QuestionProblem StatementKrish is developing a function to perform a specific array manipulation task. The goal is to remove an element from a given array of integers, 'arr', at a designated position 'p'. The position value 'p' is based on a 1-indexed system, meaning the first element is at position 1, the second at position 2, and so on.If the position is invalid, print "Invalid position!" Otherwise, print the modified array after removal.Input format :The first line of input consists of an integer n, representing the size of the array.The second line of input consists of n space-separated integers, representing the elements of the array.The third line of input consists of an integer p, representing the position to remove an element.Output format :If p is invalid, the output prints "Invalid position!"Otherwise, the output prints the array after removing the element at the specified position, separated by a space.Refer to the sample output for the formatting specifications.Code constraints :In the scenario, the test cases fall under the following constraints:1 ≤ n ≤ 101 ≤ Each element ≤1001 ≤ p ≤ nSample test cases :Input 1 :52 3 5 1 42Output 1 :2 5 1 4 Input 2 :1010 20 40 30 50 70 60 80 90 10012Output 2 :Invalid position!Input 3 :24 5 1Output 3 :5

How to delete the last three elements from an integer array?Note: In the options, n is the size of the array, and "arr" is the name of the 1D ar

Suppose you have n elements in the array 'a' numbered from 1 to n. It is possible to remove the i-th element of 'a' if the number a[i] and i are relatively co-prime i.e. gcd(a[i],i)=1. After an element is removed, the elements to the right are shifted to the left by one position.An array b with n integers such that 1≤b[i]≤n−i+1 is a removal sequence for the array a if it is possible to remove all elements of a, if you remove the b1-th element, then the b2-th, ..., then the bn-th element. For example, let a=[42,314]:[19,19] is a removal sequence: when you remove the 1-st element of the array, the condition gcd(42,19)=1 holds, and the array becomes [314];when you remove the 1-st element again, the condition gcd(314,19)=1 holds, and the array becomes empty.[2,1] is not a removal sequence: when you try to remove the 2-nd element, the condition gcd(314,2)=1 is false.An array is special if it has at least two removal sequences. For example, the array [1,2,5] is special: it has removal sequences [3,1,1] and [1,2,1]. The array [42,314] is not special: the only removal sequence it has is [1,1].You are given two integers n and m. You have to calculate the number of special arrays a such that the length of a is from 1 to n and each ai is an integer from 1 to m.Input FormatThe first line of the input contains two integers n and m.ConstraintsPrint one integer — the number of special arrays a such that the length of a is from 1 to n and each a[i] is an integer from 1 to m. Since the answer can be very large, print it modulo 998244353.Output Format2≤n≤3⋅10^51≤m≤10^12Sample Input 010 24Sample Output 0406957500Sample Input 12 4Sample Output 18

Problem Statement You are given a function, int ElementsAndIndices(int arr[], int n); The function takes an integer array 'arr' of size 'n' as its arguments. Implement the function to find and return the number of array elements which are equal to their index value in array i.e. arr[k] = k, 0 <= k < n. Note: Indexing starts from 0. Return -1 if 'arr' is empty or None in case of python Example: Input: 10 1 12 3 5 8 9 7 12 23 Output: 3 Explanation: Index Element 0 10 1 1 2 12 3 3 4 5 5 8 6 9 7 7 8 12 9 23 Elements at index {1, 3, 7} are equal to their index values {1, 3, 7} respectively. Since, these are 3 elements, thus, output is 3. The custom input format for the above case: 10 10 1 12 3 5 8 9 7 12 23 (The first line represents the size of the array, the second line represents the elements of the array) Sample input -3 0 1 3 5 7 Sample Output 1 The custom input format for the above case: 6 -3 0 1 3 5 7 (The first line represents the size of the array, the second line represents the elements of the array) Instructions : This is a template based question, DO NOT write the "main" function. Your code is judged by an automated system, do not write any additional welcome/greeting messages. "Save and Test" only checks for basic test cases, more rigorous cases will be used to judge your code while scoring. Additional score will be given for writing optimized code both in terms of memory and execution time.

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
