Any issue involving payment is very sensitive, and it is unacceptable for either party to suffer losses. So here are some important points of payment security. IAP refers to In-App Purchase, which is a payment method, rather than

1. Description of the problemFind out the number of K-large in the array, note that the array is an unordered array.　　2. Methods and Ideasis a classic algorithm problem. The solution also has several kinds, one is to sort first, then take out the number of k large, because the sorting algorithm the quickest efficiency is o(nlOgn) , so overall efficiency is o(nlOgn) 。 The second is to use the priority queue, the usage of priority queue in SLT, the internal is implemented
