035 - Sum Odds in Range

You are given two inputs: int num1; int num2; You can assume that the following: num2 > num1 ==> TRUE You are to write a program that will calculate and print out the SUM OF ODD numbers in between num1 and num2 inclusive. Your output should all be on one line, separated by spaces. Sample input/output: #1: 3 #2: 11 Output: 35 #1: 4 #2: 20 Output: 96 #1: -2 #2: 6 Output: 8 Solution 1 2 3 4 5 6 7 8..

034 - Big Number Program (From Decoding)

You are given two inputs: int num1; int num2; You can assume that the following: num2 > num1 ==> TRUE You are to write a program that will print out all the ODD numbers in between num1 and num2 inclusive. Your output should all be on one line, separated by spaces. Sample input/output: #1: 3 #2: 11 3 5 7 9 11 #1: 4 #2: 20 5 7 9 11 13 15 17 19 #1: -2 #2: 6 -1 1 3 5 Solution 1 2 3 4 5 6 7 8 9 10 11..

033 - For Loop Challenge 2 (optional)

Write code that will take in a String input and check to see if it is a palindrome or not. A palindrome means that the characters are the same forwards and backwards, ignoring spaces. Examples of palindromes: racecar was it a car or a cat I saw never odd or even rats live on no evil star Your check should be case insensitive too. For example, "Bob" is a palindrome, despite the first B being capi..

032 - For Loop Challenge 1 (optional)

The fibonacci sequence is a sequence of numbers in which the next number is the sum of the previous two numbers. The first two numbers of the fibonacci sequence are 0, 1. The first 8 numbers of the fibonacci sequence are 0, 1, 1, 2, 3, 5, 8, 13 Write some code to print out the first X numbers of the fibonacci sequence. Your output should be on one line, with each number separated by a space. You..

031 - Further For Loop Practice 7 (mIxEd CaSe)

Given the following inputs: String s; Write a for loop that will print out the string in alternating cases, with the first letter being lowercase. Keep in mind the following String methods: str.toUpperCase(); //make it uppercase str.toLowerCase(); //make it lowercase DO NOT USE .charAt()! .charAt returns a character, and you need a string in order to make it upper/lowercase. To get a letter at a..

030 - Further For Loop Practice 6 (reverse string)

Given the following inputs: String s; Write a for loop that will print out the reverse of the string. Sample input/outputs: In: manhattan out: nattahnam In: processor out: rossecorp In: racecar out: racecar Solution 1 2 3 4 5 6 7 8 9 10 11 12 13 14 import java.util.Scanner; class Bakjoon { public static void main(String[] args) { Scanner inp = new Scanner(System.in); System.out.print("In:"); Str..

029 - Further For Loop Practice 5 (printing characters)

Given the following inputs: String s; Write a for loop that will print out each letter of the string s, separated by spaces, on the same line. Sample input/outputs: In: hello out: h e l l o In: covert out: c o v e r t In: blasphemy out: b l a s p h e m y Solution 1 2 3 4 5 6 7 8 9 10 11 12 13 14 import java.util.Scanner; class Bakjoon { public static void main(String[] args) { Scanner inp = new ..

028 - Further For Loop Practice 4 (repeating X times)

Given the following inputs: int x; Write a for loop that will print out "AP CS A" x number of times, new line per print. Sample input/outputs: In: 3 AP CS A AP CS A AP CS A In: 5 AP CS A AP CS A AP CS A AP CS A AP CS A In: 1 AP CS A Solution 1 2 3 4 5 6 7 8 9 10 11 12 13 14 import java.util.Scanner; class Bakjoon { public static void main(String[] args) { Scanner inp = new Scanner(System.in); Sy..

027 - Further For Loop Practice 3 (descending)

Given the following inputs: int x; Write a for loop that will print out a series of numbers starting at one less than x and ending at 0. Sample input/outputs: In: 7 out: 6 5 4 3 2 1 0 In: 12 out: 11 10 9 8 7 6 5 4 3 2 1 0 In: 20 out:19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0 Solution 1 2 3 4 5 6 7 8 9 10 11 12 13 14 import java.util.Scanner; class Main { public static void main(String[] a..

026 - Further For Loop Practice 2 (skipping by 3s)

Given the following inputs: int x; Write a for loop that will print out a series of numbers starting at 0 and ending before x, skipping 3 each time (excluding x). Sample input/outputs: In: 7 out: 0 3 6 In: 12 out: 0 3 6 9 In: 20 out: 0 3 6 9 12 15 18 HINT: You'll want to change the increment part of the for loop! 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 import java.util.*; class Bakjoon { public stat..
