timid play bold play

timid play和bold play是两种截然不同的玩法。timid play指的是胆小怕事，畏首畏尾的玩法，往往遇到困难就退缩，不敢冒险尝试。而bold play则是大胆、果断的玩法，敢于冒险，敢于挑战自己，积极主动地去尝试新的事物和方法。

在生活中，有些人可能更倾向于timid play，他们担心未知的风险，害怕失败和受伤。他们在面对挑战时，更愿意选择稳妥的方式，很少有创新和突破。而另一些人则更喜欢bold play，他们乐于尝试新鲜事物，愿意挑战自己，敢于承担风险。他们更具备创造力和勇气，能够在竞争激烈的环境中脱颖而出。

在工作中，timid play的人可能不敢承担更大的责任，容易被淘汰或者处于不被重视的境地；而bold play的人则更有可能在竞争中脱颖而出，得到更多机会和发展空间。

总的来说，timid play和bold play都有各自的优势和劣势，关键在于在不同的情境下选择恰当的方式。生活中需要我们在遇到问题时要勇敢面对，而在一些需要慎重考虑的情况下要谨慎行事，不断学习，不断总结经验，从而找到适合自己的平衡点。

Every year the cows hold an event featuring a peculiar version of hopscotch that involves carefully jumping from rock to rock in a river. The excitement takes place on a long, straight river with a rock at the start and another rock at the end, L units away from the start (1 ≤ L ≤ 1,000,000,000). Along the river between the starting and ending rocks, N (0 ≤ N ≤ 50,000) more rocks appear, each at an integral distance Di from the start (0 < Di < L). To play the game, each cow in turn starts at the starting rock and tries to reach the finish at the ending rock, jumping only from rock to rock. Of course, less agile cows never make it to the final rock, ending up instead in the river. Farmer John is proud of his cows and watches this event each year. But as time goes by, he tires of watching the timid cows of the other farmers limp across the short distances between rocks placed too closely together. He plans to remove several rocks in order to increase the shortest distance a cow will have to jump to reach the end. He knows he cannot remove the starting and ending rocks, but he calculates that he has enough resources to remove up to M rocks (0 ≤ M ≤ N). FJ wants to know exactly how much he can increase the shortest distance *before* he starts removing the rocks. Help Farmer John determine the greatest possible shortest distance a cow has to jump after removing the optimal set of M rocks. Input Line 1: Three space-separated integers: L, N, and M Lines 2..N+1: Each line contains a single integer indicating how far some rock is away from the starting rock. No two rocks share the same position. Output Line 1: A single integer that is the maximum of the shortest distance a cow has to jump after removing M rocks Sample Inputcopy Outputcopy 25 5 2 2 14 11 21 17 4 Hint Before removing any rocks, the shortest jump was a jump of 2 from 0 (the start) to 2. After removing the rocks at 2 and 14, the shortest required jump is a jump of 4 (from 17 to 21 or from 21 to 25).

To determine the greatest possible shortest distance a cow has to jump after removing the optimal set of M rocks, we can follow these steps:

1. Read the input values for L, N, and M.
2. Read the distances of the N rocks from the starting rock and store them in a list.
3. Sort the list of distances in ascending order.
4. Calculate the initial shortest jump as the distance from the starting rock to the first rock.
5. Initialize a variable max_jump to store the maximum shortest jump.
6. Iterate over each possible combination of removing M rocks from the list of distances. We can use a nested loop to generate all combinations.
- For each combination, calculate the shortest jump after removing the selected rocks.
- Update max_jump if the current shortest jump is greater than max_jump.
7. Print the value of max_jump as the maximum shortest distance a cow has to jump after removing M rocks.

Here's an example implementation in Python:

from itertools import combinations

L, N, M = map(int, input().split())

rocks = []
for _ in range(N):
    rocks.append(int(input()))

rocks.sort()

initial_jump = rocks[0]
max_jump = 0

for remove_rocks in combinations(range(1, N + 1), M):
    jumps = [rocks[remove_rocks[i]] - rocks[remove_rocks[i - 1] - 1] for i in range(1, M)]
    jumps.append(L - rocks[remove_rocks[M - 1] - 1])
    shortest_jump = min(jumps)
    max_jump = max(max_jump, shortest_jump)

print(max_jump)

In the example input provided, the output would be `4`, which represents the maximum shortest distance a cow has to jump after removing 2 rocks.

Note: This solution uses brute force to iterate over all possible combinations of removing M rocks. The time complexity is O(N choose M), which can be large for large values of N and M.

objective = solver.Objective() for k in range(num_tasks): objective.SetCoefficient(x[i, j, k], 1) # 设置任务的权重为1 objective.SetMaximization() 逐句解释一下这是什么意思?

这段代码使用了某个求解器（solver）来定义一个优化问题的目标函数（objective）。让我们逐句来解释其含义：

1. `objective = solver.Objective()`: 这行代码创建了一个空的目标函数对象，将其赋值给名为`objective`的变量。这个目标函数将用于定义优化问题的目标。

2. `for k in range(num_tasks):`: 这是一个循环语句，它遍历了一个从0到`num_tasks-1`的范围。在每次循环中，变量`k`会被赋值为当前循环迭代的索引。

3. `objective.SetCoefficient(x[i, j, k], 1)`: 这行代码设置了目标函数中每个变量`x[i, j, k]`的系数为1。这里的`x`可能是一个变量数组，在这个循环中，对于每个任务（`k`），我们将对应的变量的系数设置为1。这样，这个目标函数将考虑所有任务的权重并尝试最大化或最小化它们。

4. `objective.SetMaximization()`: 这行代码指定了优化问题的目标是最大化。如果你想要最小化目标，可以使用`SetMinimization()`方法。

综上所述，这段代码是在使用求解器来创建一个最大化目标函数，并将所有任务的权重设置为1。这样，当我们使用该求解器求解优化问题时，它将尝试通过调整变量`x[i, j, k]`的值来最大化所有任务的权重。请注意，上述代码片段中的具体细节可能依赖于所使用的求解器库和相关约束条件的定义。
