I need exact output like this expected output and I want to pass each and every testcase for this program

When input is "python learning" output displayed is 16-25-20-8-15-14- 12-5-1-18-14-9-14-7 there is additional - after 14 digit. how to rectify this issue?

Speed Typing Test

In this assignment, let's build a Speed Typing Test by applying the concepts we learned till now.

Armstrong numbers between two intervals

Write a program to print all the Armstrong numbers in the given range

A to B(including A and B). An N-digit number is an Armstrong number if the number equals the sum of the Nth power of its digits.Input

The first line has an integer

A. The second line has an integer B.Output

Print all Armstrong numbers separated by a space.

If there are no Armstrong numbers in the given range, print

-1.Explanation

For

A = 150 and B = 200For example, if we take number 153, the sum of the cube of digits

1, 5, 3 is 1³ + 5³ + 3³ = 153.

So, the output should be

153.

Sample Input 1

Given polynomial, write a program that prints polynomial in Cix^Pi + Ci-1x^Pi-1 + .... + C1x +

The first line contains a single integer N.

Next N lines contain two integers Pi, Ci separated with space, where Pi denotes power and Ci denotes coefficient of Pi.Output

For term Cix^Pi, if the coefficient of the term Ci is 1, print x^Pi instead of 1x^Pi.Explanation

N <= 100

0 <= Pi < 1000

-1000 <= Ci <= 1000

Half Pyramid - 4

Given an integer N as a starting number and K as input, write a program to print a number pyramid of K rows as shown below.

Input

The first line of input is an integer N.

The second line of input is an integer K.

Explanation

In the example, the given starting number is 10, and the number of rows in the pyramid is 5.

So, the output should be
