birthday-wish-age-calculator

This project will have 2 classes Date & Student class. The Student class will have Date class objects in it for specific purpose, the main function will be in the Student class itself. The purpose of this project is to get user desired input and print the age and a " HAPPY BIRTHDAY " message for the person.

book-details-and-price-calculator

This program will have 3 classes namely - Date, Book, Author & a Main class. The Author class will have 2 constraints - Author Id and Name, Book class will have 3 constraints - Book Name, ID, price. Here if the book exists the program will return all the details of the book also if book is published from 2010 to 2021 then additional 25% discount will be applied in purchasing of the book.

book-details-and-price-calculators

buy-maximum-toys-possible-

Amit wants to buy some toys for his sister. He has X rupees in his pocket. But he is confused to buy which toy and seeking your help. Given an array consisting of cost of toys. Find the maximum number of toys he can buy with the amount X. Note: He can buy only 1 quantity of a particular toy.

calculate-power-of-a-number

Write a function power, which will take two integers (num,pow) as argument and return the num raised to the power pow. If pow < 0 then return -1 else return num raised to the power pow.

check-balanced-parentheses-in-an-expression

Check balanced parentheses in an expression star_border Given an expression only containing upper-case alphabets: A-Z, operators: /, * , +, - and characters: (,),{,},[,] used to mark start and end of parentheses, validate whether the parentheses are balanced or not.

convert-infix-expression-to-postfix-expression

Convert infix expression to postfix expression star_border Given an infix expression, convert the infix to postfix expression.

count-words

Write a function countWords() to count the numbers of words in a string. A word is defined as text separated by space(' ') or multiple spaces. The function will receive a string as input and return the numbers of words in this string.

counter-diagnol-traversal-

Given a n*n square matrix, traverse the matrix along its counter diagonals and print the elements.

counting-sort-implementation

I will share the basic implementation of Counting sort.

cut-the-sticks

Given an array, lengths, of N stick lengths (where each length is a positive integer), a cut operation reduces the length of each stick in the array by the length of the array's shortest stick. A stick can only be cut if it has a length ≥ 1. Complete the cutSticks() function. Your function must perform cut operations on lengths until every stick length is reduced to 0 and return an integer array, where ith element of the array denotes the individual sticks cut during the ith operation. Your function must return an integer array or list, where ith element of the array denotes the individual sticks cut during the ith operation.

decimal-to-binary

Given a decimal number n, print its binary equivalent.

evaluate-the-postfix-expression-using-stack

Evaluate the postfix expression using Stack star_border Given a postfix expression, evaluate it using stack and print the final output.

factorial-using-recursion-

Write a recursive function factorial that accepts an integer n as a parameter and returns the factorial of n, or n!. A factorial of an integer is defined as the product of all integers from 1 through that integer inclusive. For example, the call of factorial(4) should return 1 * 2 * 3 * 4, or 24. The factorial of 0 and 1 are defined to be 1. You may assume that the value passed is non-negative and that its factorial can fit in the range of type int.

fibonacci-sequence

The Fibonacci numbers are a sequence of numbers where each number after the first two is a sum of the prior two. As an illustration, here is a short sequence given starting values of (0, 1) is (0, 1, 1, 2, 3, 5, 8, 13). Write a program to generate and print the first n terms of the Fibonacci sequence where n >=1.

As an illustration, here is a short sequence given starting values of (0, 1) is (0, 1, 1, 2, 3, 5, 8, 13). Write a program to generate and print the first n terms of the Fibonacci sequence using recursion in reverse order.

find-count-of-a-number-in-a-sorted-list-with-duplicates

Find count of a number in a sorted list with duplicates star_border Given a sorted list of integers with duplicates, find the count of a given number in this list in O(log n).

find-first-occurrence-of-an-integer-in-a-sorted-list-with-duplicates-

Find first occurrence of an integer in a sorted list with duplicates star_border Given a sorted list of integers, find the position of first occurrence of a given number K in this list in O(log n) time.
