corresponds to a offset in bitmap. A uid accesses this article and sets the offset corresponding to the uid to 1. In this way, there will be no repeated access issues, and there is a ready-made method to calculate the number of BITs with a value of 1. If the website traffic is not large, the bitmap corresponding to each article is 128*128 enough. This is a bit simple, but there may be a waste of resources.

Divide and conquer the law to find the k-th number The idea of "Quick Sort" is used to find the k-th large number of a series. The second year of high school started to write fast sort, but he has never been very clear about it. He knows that it is "divide", but does not understand the details. Today, with the help of this opportunity, I read the four fast-coding methods in programming Pearl River, which ma

milliseconds for the calendar time. (This is the key to calculating the number of days for different dates) Iv. simpledateformat Simpledateformat is widely used because it can customize the date display format; (1) y indicates the year; yyyy indicates the four-digit year, such as 2011 (2) M indicates month; mm indicates two months, for example, 11. (3) d Indicates day; dd indicates two days, for example, 11. Common usage: (1) simpledateformat SDF =

Q: How does the daily script calculate the number of days in a specified month?A: In this case .... 1: function daysInMonth(iMonth, iYear) 2: { 3: return 32 - new Date(iYear, iMonth, 32).getDate(); 4: } As for why, you may understand it after careful consideration, but his ideas are indeed clever and he can't help but give me a sigh of relief.

Method 1: brute-force enumeration 2, 3, 4..., Judge in turn whether N can be divided by 2 | 3 | 5 until 1,500th #include Let's talk a little bit about the skills. The running speed is similar. If X can be divisible by 2, 3, or 5, then X must be in the form of 2y, 3Y, or 5y. Therefore, we only need to list the numbers of 2y, 3Y, and 5y in ascending order until we can list them into 1500, even if we want to solve them. Here, there may be two or three expressions satisfying at the same time.

1. There is an integer array whose elements contain positive integers and negative integers. Find the largest subset of all its child sets.For example, [12,-,-,]. The result is 63 [12,-].The complexity is O (n ).
