Little Petya loves presents. His mum bought him two strings of the same size for his birthday. The strings consist of uppercase and lowercase Latin letters. Now Petya wants to compare those two strings lexicographically. The letters' case does not matter, that is an uppercase letter is considered equivalent to the corresponding lowercase letter. Help Petya perform the comparison.InputEach of the first two lines contains a bought string. The strings' lengths range from 1 to 100 inclusive. It is guaranteed that the strings are of the same length and also consist of uppercase and lowercase Latin letters.OutputIf the first string is less than the second one, print "-1". If the second string is less than the first one, print "1". If the strings are equal, print "0".

Solution
This problem is about comparing two strings lexicographically. Here are the steps to solve this problem:
- Read the first string from the input.
- Read the second string from the input.
- Convert both strings to lowercase or uppercase. This is because we are told that the case of the letters does not matter in this comparison.
- Compare the two strings. If they are equal, print "0".
- If the first string is lexicographically smaller than the second one, print "-1".
- If the first string is lexicographically larger than the second one, print "1".
In Python, you can use the built-in function lower() or upper() to convert the strings to lowercase or uppercase respectively. You can use the comparison operators (<, ==, >) to compare the strings.
Here is a Python code snippet that solves the problem:
# read the first string
s1 = input().strip()
# read the second string
s2 = input().strip()
# convert the strings to lowercase
s1 = s1.lower()
s2 = s2.lower()
# compare the strings and print the result
if s1 < s2:
print("-1")
elif s1 == s2:
print("0")
else:
print("1")
This code first reads the two strings from the input, then converts them to lowercase. It then compares the strings and prints the result according to the problem statement.

Petya started to attend programming lessons. On the first lesson his task was to write a simple program. The program was supposed to do the following: in the given string, consisting if uppercase and lowercase Latin letters, it:deletes all the vowels,inserts a character "." before each consonant,replaces all uppercase consonants with corresponding lowercase ones.Vowels are letters "A", "O", "Y", "E", "U", "I", and the rest are consonants. The program's input is exactly one string, it should return the output as a single string, resulting after the program's processing the initial string.Help Petya cope with this easy task.InputThe first line represents input string of Petya's program.

This exercise is to test your understanding of Java Strings. A sample String declaration:String myString = "Hello World!"The elements of a String are called characters. The number of characters in a String is called the length, and it can be retrieved with the String.length() method.Given two strings of lowercase English letters, and , perform the following operations:Sum the lengths of and .Determine if is lexicographically larger than (i.e.: does come before in the dictionary?).Capitalize the first letter in and and print them on a single line, separated by a space.Input FormatThe first line contains a string . The second line contains another string . The strings are comprised of only lowercase English letters.Output FormatThere are three lines of output:For the first line, sum the lengths of and .For the second line, write Yes if is lexicographically greater than otherwise print No instead.For the third line, capitalize the first letter in both and and print them on a single line, separated by a space.Sample Input 0hellojavaSample Output 09NoHello JavaExplanation 0String is "hello" and is "java". has a length of , and has a length of ; the sum of their lengths is .When sorted alphabetically/lexicographically, "hello" precedes "java"; therefore, is not greater than and the answer is No.When you capitalize the first letter of both and and then print them separated by a space, you get "Hello Java".
The program needs to compare two given strings lexicographically and output the difference between them. (using compareTo() function)If the first string is greater than the second string, it should output a positive value, If they are equal it should output 0If the first string is less than the second string, it should output a negative valueInput format :The first line of the input consists of a string.The second line of the input consists of a string.Output format :The output should display the following constraintsNote :If (string1 > string2), it returns a positive value (the difference between the characters).If both the strings are equal lexicographically, i.e., (string1 == string2), it returns 0.If (string1 < string2), it returns a negative value (the difference between the characters).Sample test cases :Input 1 :harryharryOutput 1 :0Input 2 :helloworldOutput 2 :-15Input 3 :tiger lionOutput 3 :8
