Primality test using recursion - Code Review Stack Exchange

WebI think you need to write a second function with two parameters to determine if it's prime or not. I don't think it's possible to write the recursive function with just one parameter without using a global variable. It's probably something like; boolean isPrime(int val) { return isPrimeHelper(val, 2); } where isPrimeHelper is recursive. WebIn the above example, we have a method named factorial (). The factorial () is called from the main () method. with the number variable passed as an argument. The factorial () method is calling itself. Initially, the value of n is 4 inside factorial (). During the next recursive call, 3 is passed to the factorial () method. WebFinding factors is a good recursive assignment in java. A function of the form bool isPrime(int input) doesn't lend itself well to simple recursive decent. There are plenty of way to iterate within recursion.. but that doesn't sound like the goal. cgcc learning platform
