Example: Program to check whether input number is prime or not To understand this program you should have the knowledge offor loop,if-else statementsandbreak statement. importjava.util.Scanner;classPrimeCheck{publicstaticvoidmain(Stringargs[]){inttemp;booleanisPrime=true;Scannerscan=newScanner(System...
A prime number is a natural number greater than 1 that has no positive divisors other than 1 and itself. Program logic: If any number which is not divisible by any other number which is less than or equal to square root of that number, then it is prime number. Lets create java program...
TheprintAltPrime()method prints the alternate prime numbers upto the value passed as an argument. Do read the comments to understand the logic of the program. classJavaExample{//method for checking prime numberstaticintcheckPrime(intnum){inti,flag=0;for(i=2;i<=num/2;i++){if(num%i==0)...
//try this /* To check a prime no : the number should not be divisible in the range of sqrt(number) */ int n=4; n=Convert.ToInt32(Console.ReadLine()); bool prime = true; for(int i=2;i*i<=n;i++) { if(n%i==0) { prime=false; break; } } if(prime==true) { Co...

This same code can be applied in any languages like Python, Go Lang, Java, PHP, Node.js, Javascript, C, C++, .NET, Rust, etc with the same logic and have performance benefits. It is pretty fast based on the number of iterations needed. Performance time checks were not consistent across...
407 is not a prime number 11 times 37 is 407 Here, we have used a for..else statement to check if num is prime. It works on the logic that the else clause of the for loop runs if and only if we don't break out the for loop. That condition is met only when no factors are ...
/* This nifty little algo - (not mine) - catches prime numbers up to the "i" ubound. My analysis is that the "core" logic (not explaining the obvious functioning of the loops), is that if the inner loop counter ('j') reaches its max, then the 'i' var is prime IF the 'j' ...
