preface This article uses three examples to explain the single adjustment stack What is a monotone stack The elements in the stack are strictly or non strictly monotonically increasing or decreasing When implementing, maintain the order of elements in the stack Example 1 Acwing1978 (simple) Title Link https://www.acwing.com/problem/content ...

The following is the main body of this article, and the following cases can be used for reference. Stack chain overview (illustration) The stack can be stored in sequence or chain, which are called sequence stack and chain stack respectively. Sequential stack allocates a continuous space and requires two pointers. base points to the b ...

summary In actual development, it is often necessary to store a set (more than one) of data for later code to use. At this point, you may have heard of an Array, which can store multiple data one by one, and each element in the Array can be accessed through the Array subscript. It should be clear that Python does not have arrays, but adds ...

1. Queue 1.1 concept Queue: a special linear table that only allows inserting data at one end and deleting data at the other end. The queue has the characteristics of first in first out FIFO(First In First Out). Queue entry: the end of the insertion operation is called Tail/Rear Out of queue: the end for deletion is called Head/Front Ill ...

1, Definition and characteristics A stack is a linear table that performs insertion and deletion operations only at one end of the table (a linear table refers to a one-to-one relationship between elements rather than sequential storage and chain storage). The operation end is called the top of the stack and the other end is called the bot ...

"Li Kou" question 1673: find the most competitive subsequence (stack) Give you an integer array num and a positive integer k, and return the most competitive num subsequence with length K. A subsequence of an array is a sequence obtained by deleting some elements from the array (elements may not be deleted). In the first different ...

Here, I name it get (char x). X is the formula we enter, I set the priority of "(") as' 0 'at the lowest, followed by' + 'and' - 'as 1,' * ' ...
