💡 Problem Formulation: In Python, you may encounter a situation where you need to determine if a list or array contains a sequence of contiguous integers, even if some values are repeated. This challenge can arise in various data analysis tasks, where the continuity of data points is essential. For instance, you have an input … Read more

💡 Problem Formulation: In various programming scenarios, you might be tasked with verifying whether elements within an array follow a sequential order without any gaps. For instance, given the input array [2, 3, 4, 5, 6], the desired output should affirm that the array contains consecutive elements. Conversely, the array [4, 5, 7, 8] should … Read more

💡 Problem Formulation: The task is to determine whether the elements of an array are consecutive, ensuring that the solution adheres to time complexity O(n) and space complexity O(1), regardless of the elements being positive or negative. For example, given the array [4, 2, 5, 3, 1], the desired output is True since the numbers … Read more

💡 Problem Formulation: We are looking to determine whether we can manipulate the sum of the elements in an array to equal a specified target value (k) by applying at most three operations: adding, subtracting, or replacing elements. Given an array like [1, 2, 3] and a target sum, say k = 6, we aim … Read more

💡 Problem Formulation: We need a robust solution to determine if a number, when represented in binary, forms a palindrome. A binary palindrome is a sequence of binary digits (0s and 1s) that reads the same backward as forward. For example, the binary representation of the decimal number 9 is 1001, which is a palindrome. … Read more

💡 Problem Formulation: You may encounter a situation where you need to determine if the binary representation of two numbers are anagrams of each other. Essentially, an anagram in this context means the binary strings have the same frequency of ‘1’s and ‘0’s. For example, if you take the numbers 5 (binary 101) and 6 … Read more

💡 Problem Formulation: In various computational problems, it’s necessary to determine whether a string contains a sequence of consecutive similar elements. Specifically, we want to check if a string has ‘m’ consecutive ‘1’s or ‘0’s. For instance, given the string “001100111” and m=3, our script should indicate that the string contains a sequence of at … Read more

💡 Problem Formulation: A colindrome is a string that can be split into two parts where the second part is a mirror image of the first one. For example, ‘aabbaa’ is a colindrome because the second half ‘baa’ is a mirror of the first half ‘aab’. This article explains how to check whether a given … Read more

💡 Problem Formulation: We aim to identify if a given string is an isogram in Python. An isogram is a word in which no letter occurs more than once. For instance, the input ‘dermatoglyphics’ should return true as it is an isogram, whereas ‘programming’ should return false. Method 1: Using a Set for Comparison One … Read more

💡 Problem Formulation: In Python programming, checking if one string is the suffix of another means determining whether the second string ends with the sequence of characters that forms the first string. For instance, if ‘world’ is our suffix string and ‘hello world’ is the other string, we want our check to return True because … Read more

💡 Problem Formulation: How can we verify if a user-typed string matches a given name in Python? This question addresses the need to validate user input against expected string values. For example, confirming “Joh” is a typo of the name “John”. This is useful in user interface validation, search optimization, and more. Here, we want … Read more

💡 Problem Formulation: This article explores various methods to check whether a triangle with a positive area can be formed given three angles as input. We are assuming that the angles are in degrees, and the sum of the angles must be exactly 180 degrees for a valid triangle. The desired output is a boolean … Read more
