In Java, the IntFunction interface is a functional interface that represents a function that accepts an integer type value as an argument and returns a result of any data type. Here, the functional interface means an interface that contains only a single abstract method and exhibits single functionality. Some examples of functional interfaces are Predicate, Runnable, and Comparable interfaces. The IntFunction interface is defined in the 'java.util.function' package. In this article, we are going to explore the IntFunction Interface and its built-in methods with the help of example programs. IntFunction Interface in Java The IntFunction Interface has a ...

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. Internally, TreeMap uses a red-black tree, which is a self-balancing binary search tree. A TreeMap must implement the Comparable Interface or a custom Comparator so that it can maintain the sorting order of its elements otherwise, we will encounter a java.lang.ClassCastException. This article aims to explain how TreeMap works internally in Java. Internal Working of TreeMap in Java To understand the internal ... Read More

C compiler treats a string as an array of characters, so it is easy to remove characters of a string based on their position. The first and last position of the string have to be checked for the presence of parenthesis and have to be removed. The string can be copied into another variable and presented. There are many predefined functions in C that can be used effectively to manipulate strings. Removing a character from the starting or ending position is easily achieved in C with the help of the functions. Removing starting and ending paranthesis from string ... Read More
The title "Count of primes after converting given binary number in base between L and R" refers to a math problem that involves converting a binary number into a base between L and R and then counting the number of prime numbers that come from the conversion. In math, a prime number is a whole number that is greater than 1 and can only be divided by 1 and itself. To turn a binary number into a number with a different base, the number has to be written in a different number system. The number system's base is the number ... Read More
