Example 039: Inserting elements into an ordered list

Subject: There is a sorted array.Now enter a number and ask it to be inserted into the array according to the original law.

Program analysis: First judge whether the number is greater than the last number, and then consider the case of inserting the middle number. After the insertion, the number after this element is moved back one position in turn.

Code:

Method one:

lis = [1, 10, 100, 1000, 10000, 100000]n = int(input('insert a number: '))lis.append(n)for i in range(len(lis) - 1):if lis[i] >= n:for j in range(i, len(lis)):lis[j], lis[-1] = lis[-1], lis[j]breakprint(lis)

Method Two:

lis = [1, 10, 100, 1000, 10000, 100000]n = int(input('insert a number: '))lis.append(n)print(sorted(lis))
