Write a program that reads two words W1 and W2. Print the index at which W2 ends in W1. Input: The first line of input contains a string representing W1. The second line of input contains a string representing W2. Output: The output should be a single line containing an integer that is the index at which the word W2 ends in the word W1.

To find where word W2 ends in W1, you can use Python's rfind() method to locate the start index of W2 in W1 and then calculate the end index. If W2 is found, print the end index; if not, print -1. This approach uses basic string manipulation techniques beneficial for programming and text processing tasks.

To solve this problem, you need to determine the position at which the word W2 ends in the word W1. In programming, this can be done using string manipulation techniques. Here's a step-by-step explanation of how you might write a simple program to achieve this:

Read the Input Strings :

First, you need to capture the input strings W1 and W2. Assume these inputs will be provided line by line.


Find the Ending Index of W2 in W1 :

Use a string method to find the starting index of W2 in W1. The find method in many programming languages like Python can be used for this purpose.


Calculate the Ending Index :

Once you have the starting index of W2 in W1, the ending index can be calculated by adding the length of W2 to this starting index.


Print the Result :

Output the ending index, which essentially tells you where W2 ends in the string W1.



Here is an example of a simple program in Python:
Read the input strings
W1 = input().strip() # The first input line is W1 W2 = input().strip() # The second input line is W2
Find the starting index of W2 in W1
start_index = W1.find(W2)
Calculate the ending index
if start_index != -1: end_index = start_index + len(W2) print(end_index) else: print("W2 not found in W1") ;
