Given a sequence with a length of n, the elements in the sequence are not the same. We need to find a pair of (I, j), I = I & arr [k] Solution: RMQ + 2. Some people are violent. It is estimated that it is a data problem. Initialize rmq first. The

As you can see in the Acm thesis, learning together has at least solved many of my questions.3.3 Example 3 -- LayoutDescription:When waiting in the queue for feeding, the cows like to stand close to their friends. FJ has N (2 Some cows have a crush

Type: hash, binary search Original question:Given S, a set of integers, find the largest d such that a + B + c = d where a, B, c, and d are distinct elements of S.InputSeveral S, each consisting of a line containing an integer 1 OutputFor each S, a

This question is the same as the previous ideas. The problem is that if spfa + queue is used, it must be tle, and it can be changed to a stack. This problem cannot be solved from the beginning. It must start from the end, that is, the difference

Typical query questions. It mainly maintains the relationship between nodes. First, let's look at the path compression section: [Cpp]Int find (int x){If (fa [x] = x) return x;Int t = fa [x];Fa [x] = find (fa [x]);R [x] = (r [x] + r [t]) %

The question of determining the strongly connected component of a directed graph. determining whether any two points are connected is to determining whether the strongly connected component is one. This question is to use two DFS to calculate the

The numbers of five elements are a1, a2, a3, a4, and a5. First, a1 and a2 are added to a new row of s1, and a3 and a4 are added to a new row of s2, for s1, s2, the time is sorted in small order, and the time complexity is n ^ 2 + n ^ 2 + nlogn.Set x

This is the problem of extended discrete logarithm. XY mod Z = K, returns X, Z, K, and returns Y.When Z is a prime number, use the baby-step algorithm. However, what should I do if the modulus is not a prime number.The equation a ^ X = B % c can
