The exercises were originally meant for Python, but doing them in JavaScript, Ruby or any Lisp (Scheme, Clojure, …) should work just as well. Then the next smallest from A to C. Then put the smallest, from B, on top of the next smallest, at C. Print out the instructions needed to move the whole stack of 6 disks from A to C. Closures (a kind of function) are also essential. You can also, And, If you need to refresh your Data Structure and Algorithms skills to solve these Programming questions and exercise then check out. Create a function zip that takes an arbitrary number of sequneces, and zips them, i.e. Write a program that will print the following output 1 1 2 1 1 2 4 2 1 1 2 4 8 4 2 1 1 2 4 8 16 8 4 2 11 2 4 8 16 32 18 8 4 2 1exercise number 22. be solved using different ways like using arithmetic operators or by using a bit Admin can you post more Java programs which are used for improving programming skill and also useful for interviews(these 10 questions are good but want more and more like such questions friend....), Exercise 10 for anyone interested, simple version.public class pyramidDrawing { public static void main(String[] args) { simpleDrawing(10); arrayDrawing(10); } public static void simpleDrawing(int number) { for(int i = 1; i <= number; i++) { for(int j = 1; j <= i; j++) { System.out.print("*"); } System.out.println(); } for(int v = number; v >= 1; v--) { for(int q = 1; q <= v; q++) { System.out.print("*"); } System.out.println(); } } public static void arrayDrawing(int number) { List numere = new ArrayList(); for(int numar = 1 ; numar <= number; numar++) { numere.add(numar); } for(int i = 0; i < numere.size(); i++) { if(i % 2 == 0) { for(int j = 0; j <= i; j++) { System.out.print(numere.get(i)); } System.out.println(); } } for(int v = numere.size(); v >= 0; v--) { if(v % 2 != 0) { for(int q = 1; q <= v; q++) { System.out.print(numere.get(v-1)); } System.out.println(); } } }}, **************************************************************************************************************13335555577777779999999999999999997777777555553331, Updated one, as we no need to repeat the biggest number of stars or number for example 999999999, and also the argument in simpleDrawing(10) has to be 1,3,5,7,9,11or so on not 10 import java.util.ArrayList;import java.util.List;public class pyramidDrawing {public static void main(String[] args) {simpleDrawing(7);arrayDrawing(10);}public static void simpleDrawing(int number) {for(int i = 1; i <= number; i+=2) {for(int j = 1; j <= i; j++) {System.out.print("*");}System.out.println();}for(int v = number-2; v >= 1; v-=2) {for(int q = 1; q <= v; q++) {System.out.print("*");}System.out.println();}}public static void arrayDrawing(int number) {List numere = new ArrayList();for(int numar = 1 ; numar <= number; numar++) {numere.add(numar);}for(int i = 0; i < numere.size(); i++) {if(i % 2 == 0) {for(int j = 0; j <= i; j++) {System.out.print(numere.get(i));}System.out.println();}}for(int v = numere.size()-2; v >= 0; v--) {if(v % 2 != 0) {for(int q = 1; q <= v; q++) {System.out.print(numere.get(v-1));}System.out.println();}}}}. @oskarkv Do you have solutions for these somewhere? It should also be possible to do them in Java and C#, but it will probably not be as easy. write a program in java to accept a string from user by command line argument and display the vowel ? They are not limited to functional programming but their mathematical nature is well-suited to F# and other functional languages. If you are new to Functional Programming, then it's the best course to start with. 2. if yes = repeat the exam 3. if no = exit from the program. import java.io. 6. lower case, upper case or numeric).

It brings features like lambda expressions and Streams, which give birth to new patterns that result in clean code in Java. Good questions, can you also post answer, that would be very useful for other readers? Write switch case program to show given date(dd/mm/yy) in words format.import java.util.Scanner;class Date{ public static void main(String[] args) { String dow; String wowby; String yowby; Double n1,n2,res; Scanner scan = new Scanner (System.in); System.out.print("Enter Date (dd/mm/yy): "); String date = scan.nextLine(); String dd = date.substring(0,2); String mm = date.substring(3,5); String yy = date.substring(6,8); int d = Integer.valueOf(dd); int m = Integer.valueOf(mm); int y = Integer.valueOf(yy); boolean valid = ((d>=1) && (d<31)); //||((m>=1) && (m<12));//||((y>=00) && (y<99)); if(!valid) System.out.print("Invalid date"); else { switch (dd) { case "01": System.out.print("First of "); switch (mm) { case "01": System.out.print("January,2020"); break; Feel free to comment, ask questions if you have any doubt.
