Just make sure your solutions are correct before submiting. Do testing, come up with clever tests. Test on big numbers, on 0, do not think pretest are good. They are not. Compare answers of your solution with answers of stupid solution.
P.S. And be nice to Ms Wrong Answer After, after all, she is still woman
You need to test your solution with a boundary cases. Remember some time wrong solution pass pretest, you remember the pretest are simple test cases. Greeting and good luck for you!!!!
