In Python, the dictionary is one of the built-in data types that stores the data in the form of key-value pairs. The pair of key-value is separated by a comma and enclosed within curly braces {}. The key and value within each pair are separated by a colon (:). Each key in a dictionary is unique and maps to a value. It is an unordered, mutable data. Creating dictionary from lists In Python, we can create a dictionary by using two separate lists. One list is considered as the keys, and the second one is considered as values. We ... Read More
What is a Subarray? A subarray is a contiguous part of the array. The sum of elements in a subarray is the cumulative sum of elements of a subarray. For example: in the given array [1, 2, 3, 4, 5, 6] the subarray is [3, 4, 5]. In this article, we are given an array and need to find if any subarray has a sum equal to zero using C. Example 1 Input: arr[] = {4, 2, -3, 1} Output: Yes Explanation: The subarray {2, -3, 1} has a sum equal to 0. Example 2 ... Read More
In this article, we are given an N x N matrix, and our task is to rotate it by 90 degrees clockwise in C. Example Input: [1 2 3], [4 5 6], [7 8 9] Output: [7 4 1], [8 5 2], [9 6 3] Below are different approaches to rotate a matrix by 90 degrees in the clockwise direction: Using Brute Force Approach Using In-Place Rotation Using Brute Force Approach This is the simple and direct approach to understand and implement. In this approach, we create a ... Read More

A tuple in Python is an ordered, immutable collection that holds multiple items, supports mixed data types, and allows indexing. Since tuples cannot be modified, index slicing can exclude specific elements when needed. Conversion to a List Applying Tuple Conversion Slicing Conversion to a ... Read More
A tuple in Python is an ordered, immutable collection that stores multiple items. It supports mixed data types, allows indexing, and is commonly used for fixed data structures. Unicode String A Unicode string in Python tuple refers to a tuple containing Unicode string values or a string that includes a tuple with Unicode characters. Tuple with Unicode string Unicode string representing a tuple ... Read More
A tuple in Python is an ordered, immutable collection that stores multiple items. It supports mixed data types, allows indexing, and is commonly used for fixed data structures. Non-literal Tuple Literal Tuple Non-Literal Tuple A non-literal tuple in Python is created dynamically using code instead of being written directly with parentheses and values like (2, 4, 6). # From a list data = [2, 4, 6] t = tuple(data) print(t) # From a generator t = tuple(i for i in range(3)) # ...

The TreeMap is a class of Java Collection Framework that implements NavigableMap Interface. It stores the elements of the map in a tree structure and provides an efficient alternative to store the key-value pairs in sorted order. In other words, it always returns the elements in ascending order. However, Java provides a few ways to iterate through the TreeMap in descending order. In this article, we are going to explore the ways of iterating TreeMap in Reverse order. How to Iterate TreeMap in Reverse Order? In Java, we can use the following ways to print elements of TreeMap in reverse ... Read More
