Python Solution for Codeforces Problem 112A - Petya and Strings

Introduction

Codeforces, a hub of competitive programming challenges, offers a myriad of thought-provoking problems. Among these, Codeforces problem 112A - Petya and Strings, explores the world of string comparison. In this article, we'll delve into an optimized Python solution for this problem, providing a detailed explanation of the code's workings, and highlighting the significance of Codeforces in honing programming skills.

Codeforces Problem 112A - Petya and Strings

Codeforces problem 112A, aptly named "Petya and Strings," immerses participants in the task of string comparison, albeit in a unique manner. The problem tasks programmers with determining the lexical relationship between two strings.

Python Solution for Problem 112A - Petya and Strings

m = input().lower()
n = input().lower()
if m == n:
    print(0)
elif m > n :
    print(1)
else:
    print(-1)

Explanation of the Python Code:

1. Input Acquisition: The code begins by reading two input strings `m` and `n`. Both strings are converted to lowercase using the `.lower()` method to ensure case-insensitive comparison.

2. String Comparison Logic: The code employs a series of conditional statements to determine the lexical relationship between the two strings. The first condition checks if the strings are equal. If they are, the code prints `0` to signify that the strings are identical.

3. Lexical Comparison: If the strings are not equal, the code performs a lexical comparison using the `>` and `<` operators. If string `m` is lexicographically greater than string `n`, the code prints `1`. Conversely, if string `m` is lexicographically smaller than string `n`, the code prints `-1`.

Conclusion

Competitive programming hinges on the mastery of problem-solving techniques, exemplified by Codeforces problem 112A - Petya and Strings. The Python solution dissected above empowers programmers to intricately assess the lexical relationship between two strings. This coding endeavor underscores the importance of string manipulation and conditional logic in problem-solving.
