7-1) binary search
Enter n values (1 < = n < = 1000), n integers in non descending order and the number x to be found. Use the binary search algorithm to find x, and output the subscript (0~n-1) where x is located and the number of comparisons. If X does not exist, output - 1 and the number of comparisons.

It focuses on the threshold research methods in image segmentation, including the global threshold method and the adaptive threshold method. The manual selection method, iterative threshold selection method, maximum inter-class variance method and watershed in adaptive algorithm in the global threshold algorithm are discussed. ...

premise The demand related to data prediction is received for the first time. It can be said that it has something to do with "data mining", rather than the conventional data retrieval, query and export of duplicate disk. Therefore, it is still more motivated and interested to try to realize this demand. Because I haven't systematical ...

Sorting algorithm is a basic algorithm in computer science, and it is widely used at the same time. python functions also have built-in sorting interfaces, such as the sorted function. In actual production, the sorting algorithm we use in different scenarios will be slightly different. The selection of sorting algorithm mainly considers the ...

In the previous article, we talked about count sorting, but count sorting has a limitation, because the count array is limited. If the range of elements in the array is too large, it is unrealistic to use count sorting, and its time complexity will expand.
The way to solve the large-scale element sorting is cardinality sortin ...

Multiple measurements do not empty, burst two lines of tears QAQ
Main idea of the title: given the cards of three colors, the points of each card are $1-9 $. Specify a set of face as: 1 Three cards 2 Same color 3 The number of points is the same or increases in sequence (e.g. 555 or 678). It is now given that $n $is $13 $or $14 $, an ...

Similar to a stack, a queue is also a special linear table, and the difference from an array is also reflected in operations such as additions and deletions. The insertion operation of the queue can only be performed at the end of the queue, and the deletion operation of the queue can only be performed at the head of the ...
