the maximum value, in [6] We also talked about using two stacks to implement a queue, so we can use two stacks to implement the queue, but also can use O (1) time to get the maximum value in the stack. So the total time complexity is reduced to O (N).Scenario Three: Double-ended queue implementation. because the steps implemented in scenario two are complex, we change the idea that in the process of obtaining the maximum value, we do not put each value in the queue, but only the data that is li

logarithmic time complexity. Solution 2: On the basis of solution 1 to consider that the number of 5 can be contributed is a multiple of 5, while the index of 5 (5,25,125,... The number of contributors that can contribute 5 is exactly the value of a power (one-off,... ), Index of non 5 (10,15,20,30,,... ) can only contribute one 5. and using N divided by 5 can get how many multiples of 5 in [1,n], divided by 25 can get how many multiples of 25 ... So all the results add up to exactly how many 5
