Python Interview coding 5 With Funny Example

🔄 String Anagram Check: Are Two Strings Anagrams? (Python Solution) An anagram is when two words contain the same letters in a different order. For example, "listen" and "silent" are anagrams. 🧐 In this blog, we’ll explore different ways to check for anagrams in Python and discuss real-life applications where this can be useful! 🚀 🛠️ Method 1: Sorting Approach The simplest way to check if two strings are anagrams is by sorting their characters and comparing them. def is_anagram_sorting(str1, str2): return sorted(str1) == sorted(str2) # Sort and compare # Example Usage word1 = "listen" word2 = "silent" print(f"Are '{word1}' and '{word2}' anagrams? {is_anagram_sorting(word1, word2)}") # Output: True 🔍 Explanation (Line-by-Line) sorted(str1) → Sorts the letters of the first string. sorted(str2) → Sorts the letters of the second string. ...

➕ Two Sum Problem: Find Pairs That Sum to a Target Value (Python Solution) Given an array of numbers, our goal is to find two numbers that add up to a given target. 🚀 For example, in the array [2, 7, 11, 15] with a target of 9 , the numbers 2 and 7 form the pair. Let’s explore different ways to solve this in Python! 🛠️ Method 1: Brute Force Approach This method checks every pair in the array to find the target sum. def two_sum_brute_force(nums, target): n = len(nums) for i in range(n): for j in range(i + 1, n): if nums[i] + nums[j] == target: return [i, j] # Return indices of the two numbers return [] # No pair found # Example Usage nums = [2, 7, 11, 15] target = 9 print(f"Indices: {two_sum_brute_force(nums, target)}") # Output: [0, 1] 🔍 Explanation (Line-by-Line) for i in range(n): → Loop through each number. for j in range(i + 1, n): → Check ...

```html 🔢 How to Find the Missing Number in an Array (Python Solution) Given an array of n distinct numbers taken from 0 to n , one number is missing. Our goal is to find that missing number efficiently. 🚀 Let’s explore two different ways to solve this problem in Python! 🛠️ Method 1: Using the Sum Formula We can use the mathematical formula for the sum of the first n natural numbers: Sum = (n * (n + 1)) / 2 If we subtract the sum of the given array from this expected sum, we get the missing number. def find_missing_number(nums): n = len(nums) # Total count should be n + 1 expected_sum = (n * (n + 1)) // 2 # Formula for sum of first n numbers actual_sum = sum(nums) # Sum of elements in the given array return expected_sum - actual_sum # The difference gives the missing number # Example Usage nums = [3, 0, 1] print(f"Missing number: {find_missing_number(nums)}") # Output: 2 🔍 Explanation (Line-...

🔁 How to Check if a String is a Palindrome in Python Ever wondered if a word or phrase reads the same forward and backward? That's called a palindrome ! 😃 Words like radar , level , and madam are palindromes. In this blog, we’ll learn how to write a Python program to check for palindromes using different methods. Let’s get started! 🚀 🛠️ Method 1: Using String Slicing [::-1] The easiest way to check for a palindrome is by reversing the string and comparing it with the original. def is_palindrome(s): return s == s[::-1] # Reverse and compare # Example Usage word = "racecar" print(f"Is '{word}' a palindrome? {is_palindrome(word)}") word2 = "hello" print(f"Is '{word2}' a palindrome? {is_palindrome(word2)}") 🔍 Explanation (Line-by-Line) def is_palindrome(s): → Define a function that takes a string s as input. return s == s[::-1] → Reverse ...

🔄 1. How to Reverse a String in Python (Without and With Built-in Methods!) Have you ever wanted to flip words backward, just for fun? Or maybe you’re trying to write a secret code that only people with mirror vision can understand? 🤔 Today, we’ll explore how to reverse a string in Python using different approaches, including without built-in methods and with built-in methods (because Python is awesome). Let’s dive in! 🚀 🛠️ Method 1: Reversing a String WITHOUT Using Built-in Functions Imagine you’re eating a pizza 🍕, but instead of starting from the front, you decide to eat it backwards from the last slice to the first. That’s exactly what we do in this method! def reverse_string(s): reversed_s = "" for char in s: reversed_s = char + reversed_s return reversed_s # Example Usage word = "PIZZA" reversed_word = reverse_string(word) print(f"Original: {word} -> Reversed: {reversed_...
