In this article, we will learn about the solution and approach to solve the given problem statement.Problem statementGiven a list input , we need to find the sum of absolute difference between all pairs in a list.Enumerate() method adds a counter to an iterable and returns it in a form of enumerate object type.In this method, we have a list ‘diffs’ which contains the absolute difference.We use two loops having two variables initialized . One is to iterate through the counter and another for the list element. In every iteration, we check whether the elements are similar or not.If not, ... Read More

In this article, we will learn about the solution and approach to solve the given problem statement.Problem statementGiven list input, we need to find the largest numbers in the given list .Here we will discuss two approachesUsing sorting techniquesUsing built-in max() functionApproach 1 − Using built-in sort() functionExample Live Demolist1 = [18, 65, 78, 89, 90] list1.sort() # main print("Largest element is:", list1[-1])OutputLargest element is: 90Approach 2 − Using built-in max() functionExample Live Demolist1 = [18, 65, 78, 89, 90] # main print("Largest element is:",max(list1))OutputLargest element is: 90ConclusionIn this article, we learnt about the approach to find largest number in a list.

Structure allows us to create user defined datatype. Structure member can be primitive datatype or it can be an array of statically allocated memory. When we assign one structure variable to another then shallow copy is performed. However, there is an exception, if structure member is an array then compiler automatically performs deep copy. Let us see this with example −Example Live Demo#include #include typedef struct student {    int roll_num;    char name[128]; } student_t; void print_struct(student_t *s) {    printf("Roll num: %d, name: %s", s->roll_num, s->name); } int main() {    student_t s1, s2;    s1.roll_num = ...

Given an input string with vowels and consonants. Rearrange the string such a way that vowels and consonants occupies alternate position in final string. As we are arranging vowels and consonants at alternate position the input string must satisfy either of the following conditions −Number of vowels and consonants must be same e.g. string "individual" has 5 vowels and 5 consonants.If number of vowels are more, then difference between number of vowels and number of consonants must be 1 e.g. string "noe" has 2 vowels and 1 consonant.If number of consonants are more, then difference between number of consonants and ...

In this article, we will learn about the solution and approach to solve the given problem statement.Problem statementGiven a number we need to convert into a binary number.Approach 1 − Recursive SolutionDecToBin(num):    if num > 1:       DecToBin(num // 2)       print num % 2Exampledef DecimalToBinary(num):    if num > 1:       DecimalToBinary(num // 2)    print(num % 2, end = '') # main if __name__ == '__main__':    dec_val = 35    DecimalToBinary(dec_val)Output100011All the variables and functions are declared in the global scope as shown below −Approach 2 − Built-in SolutionExample Live Demodef ...

C++17 has extended existing if statement’s syntax. Now it is possible to provide initial condition within if statement itself. This new syntax is called "if statement with initializer". This enhancement simplifies common code patterns and helps users keep scopes tight. Which in turn avoids variable leaking outside the scope.ExampleLet us suppose we want to check whether given number is even or odd. Before C++17 our code used to look like this − Live Demo#include #include using namespace std; int main() {    srand(time(NULL));    int random_num = rand();    if (random_num % 2 == 0) {       cout

The java.util.EnumMap class is a specialized Map implementation for use with enum keys. Following are the important points about EnumMap −All of the keys in an enum map must come from a single enum type that is specified, explicitly or implicitly, when the map is created.Enum maps are maintained in the natural order of their keys.EnumMap is not synchronized. If multiple threads access an enum map concurrently, and at least one of the threads modifies the map, it should be synchronized externally.Following are the constructors of the EnumMap class −Sr.NoConstructor & Description1EnumMap(Class keyType)This constructor creates an empty enum map with the specified ...

Compare two strings using compareTo() method in Java. The syntax is as follows −int compareTo(Object o)Here, o is the object to be compared.The return value is 0 if the argument is a string lexicographically equal to this string; a value less than 0 if the argument is a string lexicographically greater than this string; and a value greater than 0 if the argument is a string lexicographically less than this string.ExampleLet us now see an example − Live Demopublic class Demo {    public static void main(String args[]) {       String str1 = "Strings are immutable";       ...

In this article, we will learn how to count the number of elements in a stream using the counting() method in Java Streams. Java Streams provide an efficient way to process data collections, and the Collectors.counting() method is useful for counting the number of elements in a stream. The counting() method is a static method of the Collectors class, which is part of the java.util.stream package. It returns a long value representing the number of elements in the stream. Counting the Number of Elements in the Stream The following are the steps to count the number of elements in the ... Read More

In this article, we will learn the findAny() method with examples in Java. The findAny() method in Java Streams is a tool that is used for fetching an arbitrary element from a stream. It provides a quick and easy way to retrieve any element without writing any conditions. This method returns a container that may or may not contain a non-null value, which is called an Optional object. What is the findAny() Method? The findAny() method retrieves any element from the stream, and the result is wrapped in an Optional object. If the stream is empty, the Optional object will ... Read More
