The random function rand() generates ten random integers between (-10,10) and saves them in the arr1 array. Query whether there is a random integer 0 among the ten random integers generated in array arr1. If yes, output "the ten random integers generated this time contain the random number 0" in the web page; if not, output in the web page "the ten random integers generated this time do not contain the random number 0".
