Nov 9, 2021 · I n this tutorial, we are going to see how to write a C program to find the largest of N numbers using while loop. Examples: Input: n = 100 Output: [2, 5] Explanation: Unique prime factors of 100 are 2 and 5. The task is to find the largest and the smallest digit of the number. This solution looks fine if there is only one query. Write an algorithm to find the sum of the largest and smallest prime numbers for the given range. An odd number is an integer that is not exactly divisible by 2. For that, we can use a primality test such as Fermat primality test or Miller-Rabin method. Jul 23, 2025 · Given an even number n (greater than 2), the task is to find two prime numbers whose sum will be equal to the given number. I would like to know some ideas on best algorithms to do this. Mar 3, 2016 · 3 I want to find the minimum set of prime numbers which would sum to a given value e. Like, 2, 3, 5, 7, 11 and the list goes on. Examples: Input: 7 Output: 2, 3, 5, 7 Input: 13 Output: 2, 3, 5, 7, 11, 13 Naive Approach: Iterate from 2 to N, and check for prime. If no such pair of prime numbers exists in the given range, return [-1, -1]. The program takes the range and finds all the prime numbers between the range and also prints the number of prime numbers. In case there are two or more numbers with the same maximum number of prime factors, find the smallest of all. Includes simple methods, full code, and practical examples. If there are Learn how to find the difference between the largest and smallest prime numbers in an array using Java. 2.

Sep 19, 2023 · Given two numbers n and k, find whether there exist at least k Special prime numbers or not from 2 to n inclusively. Examples : Input : N = 2346 Output : 6 2 6 is the largest digit and 2 is smallest Input : N = 5 Output : 5 5 Approach: An efficient approach is to find all digits in the given number and find the largest and the smallest digit. Mar 3, 2025 · We are given a list of numbers and our task is to find the largest, smallest, second largest and second smallest elements in the list. Subsets of the prime numbers may be generated with various formulas for primes. In this article, we will learn how to check whether the given number is a prime number or not in C. 9 = 7 + 2 (not 3+3+3). A Prime Number is a number that is only divisible by 1 and itself. Sep 26, 2023 · A positive integer can have multiple prime factors, our challenge is to find the largest prime factor of a number. A prime factor is a prime number that divides n exactly (without leaving a remainder). Input: 6 Output: 3 Explanation Prime factor of 6 are- 2, 3 Largest of them is '3' Input: 15 Output: 5 Method 1: The approach is simple, just factorise the given number by dividing it with the divisor of a number and keep updating the maximum prime factor. We mark all proper multiples of 2 (since 2 is the smallest prime number) as composite. The task is to write a program to find the sum of all prime elements in the given array. It will then check each number in this range to determine if it is prime, and display all the prime numbers found within these limits. Algorithm Step 1: input list element Step 2: we take a number and compare it with all other number present in the list. Mar 21, 2021 · In this tutorial, you will learn how to display all the Prime Numbers within a Range in C. Return the number as a string. Aug 23, 2010 · First thought you can find the smallest divisor d (not equal to 1 of course), then N/d will be the largest divisor you're looking for. Examples: Input: L = 6, R = 11 Output: 7 Explanation: In the range of 6 to 11 6 is divisible by 1, 2, 3 and 6.
