[Analysis] Solving the reverse order problem is similar to MergeSort. You only need to make a slight modification to MergeSort. MergeSort adopts the division and control method. If you need to sort A [p... r], then it can be divided i

Studies have found that the Ebola virus and its co-ancestor with a similar fatal close cousin, Marburg virus, is a linear virus. The linear virus has a long history that can be traced back to at least 16 million to 23 million years ago, far beyond the expectations of scientists. How does this linear virus survive today to harm humans? A virus

looking at other people's articles, I found many misunderstandings. Some people simply think that "IE is not supported!

The "prime number pair conjecture" considers "There are infinite numbers of adjacent prime numbers with a difference of 2 ".

Question: There are 150000 numbers and 10000 operations. Change the number of I to x each time, and question the number of backward pairs after each operation. Solution 1: Tree array + treap. Each element of the tree array is a tree. In this way, you can query the number of elements less than or equal to k in the previous item in lognlogn, when an element mage changes, you only need to delete the elements from the corresponding treap in the tree arra

Obtain all the positive integer pairs so that their maximum approximate number is n, and the minimum public multiple is m. The general idea is to find all the positive integer pairs so that their maximum approximate number is n, and the minimum public factor is m. (1 The problem can be converted to: Set a and B to the integer pair, where n, a, B, and m can all be divided by n, the question is converted t
