Problem Statement

You are trying to implement collision detection in a 3D game.

In a 3-dimensional space, let C(a,b,c,d,e,f) denote the cuboid with a diagonal connecting (a,b,c) and (d,e,f), and with all faces parallel to the xy-plane, yz-plane, or zx-plane.
(This definition uniquely determines C(a,b,c,d,e,f).)

Given two cuboids C(a,b,c,d,e,f) and C(g,h,i,j,k,l), determine whether their intersection has a positive volume.

Constraints

• 0 \leq a < d \leq 1000
• 0 \leq b < e \leq 1000
• 0 \leq c < f \leq 1000
• 0 \leq g < j \leq 1000
• 0 \leq h < k \leq 1000
• 0 \leq i < l \leq 1000
• All input values are integers.

Sample Input 1

0 0 0 4 5 6
2 3 4 5 6 7

Sample Output 1

Yes

The positional relationship of the two cuboids is shown in the figure below, and their intersection has a volume of 8.

Sample Input 2

0 0 0 2 2 2
0 0 2 2 2 4

Sample Output 2

No

The two cuboids touch at a face, where the volume of the intersection is 0.

Sample Output 3

Yes

Problem Statement

You are given strings S and T consisting of lowercase English letters. Determine whether T is a (contiguous) substring of S.

A string Y is said to be a (contiguous) substring of X if and only if Y can be obtained by performing the operation below on X zero or more times.

• Do one of the following.
  • Delete the first character in X.
  • Delete the last character in X.

For instance, tag is a (contiguous) substring of voltage, while ace is not a (contiguous) substring of atcoder.

Constraints

• S and T consist of lowercase English letters.
• 1 \le |S|,|T| \le 100 (|X| denotes the length of a string X.)

Sample Input 1

voltage
tag

Sample Output 1

Yes

tag is a (contiguous) substring of voltage.

Sample Input 2

atcoder
ace

Sample Output 2

No

ace is not a (contiguous) substring of atcoder.

Sample Input 3

gorilla
gorillagorillagorilla

Sample Output 3

No

Sample Input 4

toyotasystems
toyotasystems

Sample Output 4

Yes

It is possible that S=T.

Problem Statement

We have a multiset of integers S, which is initially empty.

Given Q queries, process them in order. Each query is of one of the following types.

• 1 x: Insert an x into S.

• 2 x c: Remove an x from S m times, where m = \mathrm{min}(c,( the number of x's contained in S)).

• 3 : Print ( maximum value of S)-( minimum value of S). It is guaranteed that S is not empty when this query is given.

Constraints

• 1 \leq Q \leq 2\times 10^5
• 0 \leq x \leq 10^9
• 1 \leq c \leq Q
• When a query of type 3 is given, S is not empty.
• All values in input are integers.

The multiset S transitions as follows.

• 1-st query: insert 3 into S. S is now \lbrace 3 \rbrace.
• 2-nd query: insert 2 into S. S is now \lbrace 2, 3 \rbrace.
• 3-rd query: the maximum value of S = \lbrace 2, 3\rbrace is 3 and its minimum value is 2, so print 3-2=1.
• 4-th query: insert 2 into S. S is now \lbrace 2,2,3 \rbrace.
• 5-th query: insert 7 into S. S is now \lbrace 2, 2,3, 7\rbrace.
• 6-th query: the maximum value of S = \lbrace 2,2,3, 7\rbrace is 7 and its minimum value is 2, so print 7-2=5.
• 7-th query: since there are two 2's in S and \mathrm{min(2,3)} = 2, remove 2 from S twice. S is now \lbrace 3, 7\rbrace.
• 8-th query: the maximum value of S = \lbrace 3, 7\rbrace is 7 and its minimum value is 3, so print 7-3=4.

If the given queries do not contain that of type 3, nothing should be printed.

Problem Statement

You are given an integer sequence A=(A_1,A_2,\dots,A_N) of length N.

Find the maximum value of \displaystyle \sum_{i=1}^{M} i \times B_i for a contiguous subarray B=(B_1,B_2,\dots,B_M) of A of length M.

Notes

A contiguous subarray of a number sequence is a sequence that is obtained by removing 0 or more initial terms and 0 or more final terms from the original number sequence.

For example, (2, 3) and (1, 2, 3) are contiguous subarrays of (1, 2, 3, 4), but (1, 3) and (3,2,1) are not contiguous subarrays of (1, 2, 3, 4).

Constraints

• 1 \le M \le N \le 2 \times 10^5
• - 2 \times 10^5 \le A_i \le 2 \times 10^5
• All values in input are integers.

Sample Input 1

4 2
5 4 -1 8

Sample Output 1

15

When B=(A_3,A_4), we have \displaystyle \sum_{i=1}^{M} i \times B_i = 1 \times (-1) + 2 \times 8 = 15. Since it is impossible to achieve 16 or a larger value, the solution is 15.

Note that you are not allowed to choose, for instance, B=(A_1,A_4).

Constraints
