Python Implementation 1-9 array form result 100 for all computational formula examples, python1-9
Problem:
Write one in 1, 2 ,..., 9 (the sequence cannot be changed) insert + or-between numbers or do nothing, so that the calculation result is always 100 of the program and al
Problem:Write a program that inserts + or-or nothing between 1,2,...,9 (the order cannot be changed), so that the result of the calculation is always 100 and outputs all the possibilities. For example: 1 + 2 + 34–5 + 67–8 + 9 = 100.From functools Import reduceoperator = { 1: ' + ', 2: '-', 0: '}base = [' 1 ',
Most of the answers found on the Internet are: 99 + 9/9;
My ideas:
1): 9 + 9/9 = 10
2): 9 = 3 under the root number
3): The 3rd power of 10 = 1000
4): 1000 = 10 under the three root numbers
5): 10 square =
[Programmer interview question selection 100 questions] 9. The last k nodes in the linked list, programmer nodes
Question
Enter a one-way linked list and output the last k nodes in the list. The last 0th nodes of the linked list are the tail pointer of the linked list.
Train of Thought 1
Because it is a one-way linked list, there is only a pointer from the past to the next, instead of a pointer from the ne
