WebLogic To Find Prime Factors of a Number using Recursion We pass the user input number and 2 to the recursive function pfactors_rec (). We pass 2 as count value because 2 is the first prime number. So we initialize 2 to count and we change the value of count inside pfactors_rec () function. Inside pfactors_rec () function WebFeb 2, 2011 · the problem is your recursive implementation. use this: public static ArrayList primeFactors (int n) { if (isPrime (n)) { list.add (n); return list; } int i = 1; while (true) { if (n % (i+=2) == 0) { if (isPrime (i)) { n = n / i; list.add (i); i = 1; } } if (i> Math.sqrt (n)) break; } list.add (n); return list; } Share

Using Recursion. In the above approach we are finding the size of the linked list first and then use the array to store the elements which make the code look longer.
WebJan 30, 2016 · I found your problem. You have the potential to make two recursive calls for each time you call primeNumberList.. After you return from primeNumberList(n, m, z+1); (under the innermost else) you still can go on to print a prime and do a call to primeNumberList(n+1, m, z);.This is not the behavior you want, you want to return … WebOct 15, 2015 · 3 Answers Sorted by: 4 You use post increment i++ in your function parameter. This absolutely does nothing. Because the post increment occurs after execution. So your i variable is never incremented and makes infinite recursion which gives you segmentation fault. You can fix it with pre-increment ++i or call function with i+1.
