C++ (Cpp) collatz_len Examples

Example #1

File: problem_14.cpp Project: mk12/euler

long solve() {
	long n = 0;
	long max_len = 0;
	for (long i = 1; i < 1000000; ++i) {
		const long len = collatz_len(i);
		if (len > max_len) {
			n = i;
			max_len = len;
		}
	}
	return n;
}

Example #2

File: 14.c Project: mjnichol/Euler-Solutions

int main(){

  int largest_chain = 0;
  int num = 0;
  int len = 0;
  long int i; 

  for(i = 1 ; i < 999999 ; i++){

    len = collatz_len(i);
    if(len > largest_chain){
      num = i;
      largest_chain = len;
    }
  }

  printf("The largest collatz chain is %d and is caused by the number %d\n", largest_chain, num);

  return 0;
