Question: Love Letter in Python

Description: You write a love letter to your friend. However , before your friend can read it, someone else takes it and rotates the characters of each words left to right K times. Find the number of words that remain the same even after this shifting of letters.

Input Specification: 

Input1: String of words                                                                                                                  Input2: K, number of times rotation happens

Output Specification:

Your function should return the number of correct words.

Example 1:
String:loHel endFri
K:3
Output:0
Expalation:Here "loHel endFri" is a rotated string so the original string was "Hello Friend" which is not correct. Hence the output will be 0.

Example 2:
String:Hello dFrien
K:5
Output:1
Expalation:Here "Hello dFrien" is a rotated string so the original string was "Hello Friend" so here one word Hello is remain same after rotation so the final output will be 1.

If you want to understand this program easily then you must have knowledge of the following topics:

 

1.For loop

2.If statement

3.Function

4.String function

Program: 

Here is the complete code of this program if you want to run this just copy the code and paste it into an editor and run it to check output.

#define function to rotate word
def rotateWord(str,k):
    #splitting the string
    strRotate = str.split()
    #loop for number of rotation
    for i in range(0,k):
     #loop for number of words
     for j in range(0, len(strRotate)):
        #shifting 1 character from left to right
        strRotate[j] = strRotate[j][1:] + strRotate[j][0]
    #initializing counter
    count = 0
    #loop for getting rotating words
    for k in range(0, len(strRotate)):
        #checking rotating words in original string
        if strRotate[k] in str:
            #incrementing counter
            count+=1
    print(count)
#calling rotateword function
rotateWord("adaada", 3)
rotateWord("loHel endFri", 3)
rotateWord("Hello dFrien", 5)
"""
Output
1
0
1
