Question

Display the given series in Python.
2 3 2 3 2 3 . . . . . .N terms.

Don't use any conditional constructs or arrays or strings. Use numeric approach in solving. ​

Answer 1

We have to write a Python program to display 2 3 2 3 .... following series till n terms.

Restrictions:-

• No conditional construct
• No arrays
• No strings

(since arrays and lists are different, here we can use lists)

Main concept:-

On dividing integers (considering only whole numbers here) by 2, the remainder is in the pattern of 0 1 0 1 ....

We observe that,

• 0 + 2 = 2
• 1 + 2 = 3
• 0 + 2 = 2
• 1 + 2 = 3

and so on.

Required program:-

print(*[n%2 + 2 for n in range (0, (int(input("Enter the number of terms: "))))])

Output:-

Enter the number of terms: 5

2 3 2 3 2

Algorithm:-

• Taking input from the user about the number of terms of the series to be printed.
• Using the for loop and the range function to iterate the loop the required number of times.
• Storing the values of n%2 + 2 as the for loop iterates, in a list.
• Unpacking the list using * and printing the required pattern.
