Provide a correct Python 3 solution for this coding contest problem.
Summer vacation ended at last and the second semester has begun. You, a Kyoto University student, came to university and heard a rumor that somebody will barricade the entrance of your classroom. The barricade will be built just before the start of the A-th class and removed by Kyoto University students just before the start of the B-th class. All the classes conducted when the barricade is blocking the entrance will be cancelled and you will not be able to attend them. Today you take N classes and class i is conducted in the t_i-th period. You take at most one class in each period. Find the number of classes you can attend.

Provide a correct Python 3 solution for this coding contest problem.
Stack is a container of elements that are inserted and deleted according to LIFO (Last In First Out).
For $n$ stack $S_i$ ($i = 0, 1, ..., n-1$), perform a sequence of the following operations.
* push($t$, $x$): Insert an integer $x$ to $S_t$.
* top($t$): Report the value which should be deleted next from $S_t$. If $S_t$ is empty, do nothing.
* pop($t$): Delete an element from $S_t$. If $S_t$ is empty, do nothing.
In the initial state, all stacks are empty.

Stack is a container of elements that are inserted and deleted according to LIFO (Last In First Out).
For $n$ stack $S_i$ ($i = 0, 1, ..., n-1$), perform a sequence of the following operations.
* push($t$, $x$): Insert an integer $x$ to $S_t$.

Hiking club "Up the hill" just returned from a walk. Now they are trying to remember which hills they've just walked through.
It is known that there were N stops, all on different integer heights between 1 and N kilometers (inclusive) above the sea level. On the first day they've traveled from the first stop to the second stop, on the second day they've traveled from the second to the third and so on, and on the last day they've traveled from the stop N - 1 to the stop N and successfully finished their expedition.
They are trying to find out which heights were their stops located at. They have an entry in a travel journal specifying how many days did they travel up the hill, and how many days did they walk down the hill.
Help them by suggesting some possible stop heights satisfying numbers from the travel journal.
Input
In the first line there is an integer non-negative number A denoting the number of days of climbing up the hill. Second line contains an integer non-negative number B β the number of days of walking down the hill (A + B + 1 = N, 1 β€ N β€ 100 000).

Output N space-separated distinct integers from 1 to N inclusive, denoting possible heights of the stops in order of visiting.

Omkar is building a waterslide in his water park, and he needs your help to ensure that he does it as efficiently as possible.
Omkar currently has n supports arranged in a line, the i-th of which has height a_i. Omkar wants to build his waterslide from the right to the left, so his supports must be nondecreasing in height in order to support the waterslide. In 1 operation, Omkar can do the following: take any contiguous subsegment of supports which is nondecreasing by heights and add 1 to each of their heights.
Help Omkar find the minimum number of operations he needs to perform to make his supports able to support his waterslide!
An array b is a subsegment of an array c if b can be obtained from c by deletion of several (possibly zero or all) elements from the beginning and several (possibly zero or all) elements from the end.
An array b_1, b_2, ..., b_n is called nondecreasing if b_iβ€ b_{i+1} for every i from 1 to n-1.
Input
Each test contains multiple test cases. The first line contains the number of test cases t (1 β€ t β€ 100). Description of the test cases follows.
The first line of each test case contains an integer n (1 β€ n β€ 2 β
10^5) β the number of supports Omkar has.
The second line of each test case contains n integers a_{1},a_{2},...,a_{n} (0 β€ a_{i} β€ 10^9) β the heights of the supports.
It is guaranteed that the sum of n over all test cases does not exceed 2 β
10^5.
Output
For each test case, output a single integer β the minimum number of operations Omkar needs to perform to make his supports able to support his waterslide.

Omkar is building a waterslide in his water park, and he needs your help to ensure that he does it as efficiently as possible.
Omkar currently has n supports arranged in a line, the i-th of which has height a_i. Omkar wants to build his waterslide from the right to the left, so his supports must be nondecreasing in height in order to support the waterslide. In 1 operation, Omkar can do the following: take any contiguous subsegment of supports which is nondecreasing by heights and add 1 to each of their heights.
Help Omkar find the minimum number of operations he needs to perform to make his supports able to support his waterslide!
An array b is a subsegment of an array c if b can be obtained from c by deletion of several (possibly zero or all) elements from the beginning and several (possibly zero or all) elements from the end.
An array b_1, b_2, ..., b_n is called nondecreasing if b_iβ€ b_{i+1} for every i from 1 to n-1.
Input
Each test contains multiple test cases. The first line contains the number of test cases t (1 β€ t β€ 100). Description of the test cases follows.
The first line of each test case contains an integer n (1 β€ n β€ 2 β
10^5) β the number of supports Omkar has.
The second line of each test case contains n integers a_{1},a_{2},...,a_{n} (0 β€ a_{i} β€ 10^9) β the heights of the supports.
It is guaranteed that the sum of n over all test cases does not exceed 2 β
10^5.
Output
For each test case, output a single integer β the minimum number of operations Omkar needs to perform to make his supports able to support his waterslide.

Omkar wants to build his waterslide from the right to the left, so his supports must be nondecreasing in height in order to support the waterslide. In 1 operation, Omkar can do the following: take any contiguous subsegment of supports which is nondecreasing by heights and add 1 to each of their heights.
Help Omkar find the minimum number of operations he needs to perform to make his supports able to support his waterslide!
An array b is a subsegment of an array c if b can be obtained from c by deletion of several (possibly zero or all) elements from the beginning and several (possibly zero or all) elements from the end.
An array b_1, b_2, ..., b_n is called nondecreasing if b_iβ€ b_{i+1} for every i from 1 to n-1.
Input
Each test contains multiple test cases. The first line contains the number of test cases t (1 β€ t β€ 100). Description of the test cases follows.
The first line of each test case contains an integer n (1 β€ n β€ 2 β
10^5) β the number of supports Omkar has.
The second line of each test case contains n integers a_{1},a_{2},...,a_{n} (0 β€ a_{i} β€ 10^9) β the heights of the supports.
It is guaranteed that the sum of n over all test cases does not exceed 2 β
10^5.
Output
For each test case, output a single integer β the minimum number of operations Omkar needs to perform to make his supports able to support his waterslide.

Note
The subarray with which Omkar performs the operation is bolded.
In the first test case:
* First operation:
[5, 3, 2, 5] β [5, 3, 3, 5]
* Second operation:
[5, 3, 3, 5] β [5, 4, 4, 5]
* Third operation:
[5, 4, 4, 5] β [5, 5, 5, 5]
In the third test case, the array is already nondecreasing, so Omkar does 0 operations.

Evaluate the correctness of the submitted Python 3 solution to the coding contest problem. Provide a "Yes" or "No" response.
Omkar is building a waterslide in his water park, and he needs your help to ensure that he does it as efficiently as possible.
Omkar currently has n supports arranged in a line, the i-th of which has height a_i. Omkar wants to build his waterslide from the right to the left, so his supports must be nondecreasing in height in order to support the waterslide. In 1 operation, Omkar can do the following: take any contiguous subsegment of supports which is nondecreasing by heights and add 1 to each of their heights.
