Reverse Alternate Words in Sentence

Given a sentence, write a program to reverse the alternate words in the sentence and print it.

Reverse the first word and respective alternative words.

Input

The input will be a single line containing a sentence.

Output

The output should be a single line containing the sentence with the alternate words reversed.

Explanation

For example, if the given sentence is

Sun rises in the east and sets in the west The alternate words which need to be reversed are (Sun, in, east, sets, the), by reversing these words the output should be nuS rises ni the tsae and stes in eht west

Sample Input 1

Sun rises in the east and sets in the west

Sample Output 1

nuS rises ni the tsae and stes in eht west

Sample Input 2

The car turned the corner

Sample Output 2

ehT car denrut the renroc

Question 2 - Do it on computer, do any rough work required on paper.

a) Make a class with name as your university registration ID e.g. class F20200657890, with the following members:

1. char [] name
2. Float number
3. int x_val
4. int y_val
5. Constructor without any parameter
6. Constructor with all four parameters to set
7. Copy constructor with proper deep copy
8. Destructor
9. Total 8, Set and Get functions, for each of Name, Number, x_val, and y_val.
10. Operator + overload
11. Operator << overload as friend function

b) Write main for the class, to demonstrate constructing two objects and using each of the member functions at least once. If you miss using any single function you lose some marks.

Given two polynomials A and B, write a program that adds the given two polynomials A and B.

The first line contains a single integer M.

Next M lines contain two integers Pi, Ci separated with space, where Pi denotes power and Ci denotes co-efficient of Pi for polynomial A.

After that next line contains a single integer N.

Next N lines contain two integers Pj, Cj separated with space, where Pj denotes power and Cj denotes co-efficient of Pj for polynomial B.

If M = 4 and for polynomial A

For power 0, co-efficient is 5

For power 1, co-efficient is 0

For power 2, co-efficient is 10

For power 3, co-efficient is 6.

Then polynomial A represents "6x^3 + 10x^2 + 5", the polynomial B represents "4x^2 + 2x + 1" and the addition of A and B is "6x^3 + 14x^2 + 2x + 6"

Please help me rearrange this code again and please correct it. I can't run it. Thank you!

n = int(input())

for i in range(n):

  1st = list(map(int,input().split()))

  lst1 = lst[1:]

Secret Message - 2
Given a string, write a program to print a secret message that replaces characters with numbers 'a' with 1, 'b' with 2, ..., 'z' with 26 where characters are separated by '-'.

Note: You need to replace both uppercase and lowercase characters. You can ignore replacing all characters that are not letters.


a	b	c	d	e	f	g	h	i	j
1	2	3	4	5	6	7	8	9	10


k	l	m	n	o	p	q	r
11	12	13	14	15	16	17	18


s	t	u	v	w	x	y	z
19	20	21	22	23	24	25	26
Input

The input will be a string in the single line containing spaces and letters (both uppercase and lowercase).
Output

The output should be a single line containing the secret message. All characters in the output should be in lower case.
Explanation

For example, if the given input is "python", "p" should replaced with "16", similarly"y" with "25","t" with "20","h" with "8","o" with "15","n" with "14". So the output should be "16-25-20-8-15-14".
