Java program to divide a string in \'N\' equal parts
In this article, we will understand how to divide a string into 'N' equal parts using Java. If the string's length is divisible by N, the string will be split evenly into N parts; otherwise, a message will be displayed indicating that the string cannot be divided into N equal parts. This is demonstrated using both a simple main method and an encapsulated approach. Problem Statement Write a program in Java to divide a string into 'N' equal parts. Below is a demonstration of the same − Input Input string: Java Program is fun! Output The length of the string ...
Read MoreJava program to check if a point is on the left or right side of a line
A line consists of an infinite number of points. In two-dimensional coordinate system we can define every point with two values i.e. X and Y. A point basically situated on the left side or right side or it can be on the line itself and this can be defined only if we have the coordinates of it. In this program we are going to use the cross-product method to find the direction of the point. Cross- Product method is used to find the third vector from two vectors by cross multiplying both the vectors. In our case if we cross ...
Read MoreJava code to print common characters of two strings in alphabetical order
In this article, we will learn to print common characters of two strings in alphabetical order using Java. The program uses arrays to count how often each letter appears in both strings and then compares these counts to identify the common characters. Problem Statement Write a Java program to print common characters of two strings in alphabetical order − Input my_str_1 = "itsasample" my_str_2 = "thisisasample" Output The common characters between the two strings in alphabetical order is :aaeilmpsst Steps to print common characters of two strings in alphabetical order Following are the steps to print common characters of two strings ...
Read MoreJava program to interchange elements of first and last in a matrix across columns
In this article, we will understand how to interchange elements of first and last in a matrix across columns in Java. The matrix has a row and column arrangement of its elements. A matrix with m rows and n columns can be called as m × n matrix. Individual entries in the matrix are called elements and can be represented by a[i][j] which suggests that the element a is present in the ith row and jth column. Problem Statement Write a Java program to interchange elements of first and last in a matrix across columns. Input The matrix is defined as: ...
Read MoreGenerate pseudo-random numbers in Python
Many computer applications need random numbers to be generated. However, none of them generate an actual random number. Python, like any other programming language, uses a pseudo-random generator. Python’s random generation is based on the Mersenne Twister algorithm that produces 53-bit precision floats. The technique is fast and thread-safe but not suitable for cryptographic purposes. Python’s standard library contains the random module which defines various functions for handling randomization. The following functions handle random integer number generation. random.seed() − This function initializes the random number generator. ...
Read MoreJava Program to display upper triangular matrix
In this article, we will understand how to display an upper triangular matrix of a given matrix in Java. A matrix has row and column arrangement of its elements. A matrix with m rows and n columns can be called as m × n matrix. And, the term upper triangular matrix refers to a matrix whose all elements below the main diagonal are 0. Example Scenario: Input: matrix = { 2, 1, 4 }, { 1, 2, 3 }, { 3, 6, 2 } Output: upptri_mat = 2 1 4 0 2 3 0 0 2 Using ...
Read MoreJava program to check order of characters in string
You are given a String, your task is to write a program in Java that checks the order of its characters. If the order is previously defined, you have to check if the characters are in the given order otherwise check for alphabetical order. Let's understand the problem statement with an example − Example Scenario: Input: str = "abcmnqxz"; Output: res = TRUE The given string is in alphabetical order. Using Iteration In this approach, use a for loop to iterate over the string and check if the value of character at the current place and the previous ...
Read MoreJava program to iterate through each character of the string.
In this article, we will understand how to iterate through each character of the string using Java. The string is a datatype that contains one or more characters and is enclosed in double quotes (“ ”). Char is a datatype that contains an alphabet an integer or a special character. Problem Statement Write a program to Iterate through each character of the string. Below is a demonstration of the same − Input The string is defined as: Java Program Output The characters in the string are: J, a, v, a, , P, r, o, g, r, a, m, Different approaches ...
Read MoreJava program to print distinct permutations of a string
In this article, we will learn how to generate and print all distinct permutations of a given string using Java. Permutations are rearrangements of characters in a string, and this program will ensure that no duplicate permutations are printed. The method works by checking each rearrangement and avoiding any repeats. Problem Statement Write a program in Java to print distinct permutations of a given string − Input my_str = "mnqm" Output The distinct permutations of the string are[mnqm, nmqm, nqmm, mqnm, qmnm, qnmm, mqmn, qmmn, mnmq, nmmq, mmnq, mmqn] Steps to print distinct permutations of a string Following are the ...
Read MoreJava program to calculate sum of squares of first n natural numbers
In this article, you will learn to write a program in Java to calculate the sum of squares of first n natural numbers. This program efficiently computes the sum using a mathematical formula − (val * (val + 1) / 2) * (2 * val + 1) / 3 Problem Statement Write a program in Java to calculate the sum of squares of first n natural numbers, where n is a user-defined value. Input val = 8 Output The sum of squares of first 8 natural numbers is204 Steps to calculate sum of squares of first n natural numbers Following are ...
