Input format :The input consists of a single integer, n.Output format :The output displays the sum of consecutive numbers from 1 to n (exclusive), doubling each number before adding.

Input format :The input consists of three space-separated integers values A, B, and C, representing the first term 'A' of the arithmetic sequence, 'B' to check, and the common difference 'C' of the arithmetic sequence.Output format :The output displays 1 if 'B' is present in the arithmetic sequence, otherwise, it displays 0.

Input format :The input consists of a single line:The line contains an integer denoting n.The input will be read from the STDIN by the candidate.Output format :Print’1’ if n is a perfect number, else print the sum of the proper divisors of n.The output will be matched to the candidate’s output printed on STDOUT

Write a program to accept an integer N and print the sum of first N odd numbersInput Format:An integer range is given inputOutput Format:Print only calculated sum.Constraints:1 <= N <= 10^16 Sample Input 1:2Sample Output 1:4Sample Input 2:10Sample Output 2:100

You need to create an app that calculates the sum of the numbers 1 to N, where N is taken from input.For example, for the number 5, the output should be 15, because 1+2+3+4+5=15.

James, a mathematics teacher, is developing a programming exercise to help his students practice continuously summing the digits of a number until it becomes a single-digit integer. He wants to create a simple program using a 'while' loop that takes a positive integer input and generates the final single-digit result. Input format :The input consists of a positive integer n.Output format :The output prints "The single-digit sum of n is Y." where n is the input integer and Y is its single-digit sum.Refer to the sample output for formatting specifications.Code constraints :1 ≤ n ≤ 1010Sample test cases :Input 1 :456Output 1 :The single-digit sum of 456 is 6.Input 2 :999Output 2 :The single-digit sum of 999
