Enter a string and print all characters in odd bits (subscripts are characters in bits 1, 3, 5, 7...) For example: input * *'abcd1234 '* * output * *'bd24'** # str1 = input('Please enter a string: ') str1 = 'abcd1234' for index in range(1 ,len(str1)+1,2): print(str1[index],end='') print() Enter the user name and judge whether the user na ...

1. Problem Description: Let the middle order traversal of a binary tree with n nodes be (1, 2, 3,..., n), where the numbers 1, 2, 3,..., n are the node numbers. Each node has a score (all positive integers). Note that the score of the ith node is di, and each subtree of the tree and its subtree has a bonus. The bonus calculation method of any ...

summary It is mainly used to solve the an=b(mod p) problem and solve the minimum non negative integer n to satisfy the left formula. Ordinary BSGS can solve the case of a and P coprime, and extended BSGS can solve the case of non coprime Common BSGS Problem solving steps 1. Take m=ceil(sqrt §) (rounded up). If the solution exists, ...

New features in C++11 Article catalog 1, Range based for loop C++ 11 provides a special version of the for loop. In many cases, it can simplify the processing of arrays, which is the range based for loop. When working with an array using a range based for loop, the loop can automatically iterate once for each element in the ...

6.1 example: Digital triangle   [problem description] there is a digital triangle with layer number n (n ≤ 1000) (as shown in the figure below). There is an ant walking down from the top floor. When walking down one level, it can go down left or right. Find the maximum value of the sum of the numbers it passes through after going to th ...
