1. Prime number algorithm A prime number (P) is a number greater than 1 whose only factors are 1 and the number (P) itself. Generally, we can determine a number is prime or not in below steps: 2 is only prime number which is also even number. So, if given number N is 2 the ...

This java program will read an integer numbers and find its prime factors, for example there is a number 60, its primer factors will be 2, 3 and 5 (that are not divisible by any other number).package com.includehelp; import java.util.HashSet; import java.util.Scanner; import java....

In this java program, we are reading an integer array of N elements and finding second smallest element among them.
I know, that in java there is method n.nextProbablePrime(), that find first prime number after n and it's complexity is like O(n^(1/3)), but I don't know, how it works. →Reply sammyMaX 10 years ago,#| 0 You can use the Miller-Rabin test, which applies Fermat's Little The...
