Answer to Question #347483 in Python for Ching

Question

Minimize the cost of an array where

cost = summation of square of difference of two consecutive array elements.

ex:

arr = [1,2,3,4]

sum = (1-2)^2 + (2-3)^2 + (3-4)^2

Output = 3

if I insert any element in the range of (1 to 10^5) between any two items of the array then it will give some other value, like this I have to give the minimum cost possible by inserting a number.

Answer 1

entered_list = input("Enter a list, separating numbers with spaces: ").split()

test_list = list(map(int, entered_list))

cost = [((a - b) ** 2) for a, b in zip(test_list, test_list[1:])]

print("Cost: ", sum(cost))
