Explanation:
In Javascript, you can accept an input value by using the prompt() function and saving the input into a variable. In the following lines of code, I have declared the three variables at the beginning and then prompted the user to enter a value for each and saved the values in the correct variables. In Javascript length is a keyword so I used len instead.
let base, height, len;
base = prompt("Enter Base value: ");
height = prompt("Enter Height value: ");
len = prompt("Enter Length value: ");
Answer:
The solution code is written in Java
- public static void checkCommonValues(int arr1[], int arr2[]){
- if(arr1.length < arr2.length){
- for(int i = 0; i < arr1.length; i++){
- for(int j = 0; j < arr2.length; j++){
- if(arr1[i] == arr2[j]){
- System.out.print(arr1[i] + " ");
- }
- }
- }
- }
- else{
- for(int i = 0; i < arr2.length; i++){
- for(int j = 0; j < arr1.length; j++){
- if(arr2[i] == arr1[j]){
- System.out.print(arr2[i] + " ");
- }
- }
- }
- }
- }
Explanation:
The key idea of this method is to repeated get a value from the shorter array to check against the all the values from a longer array. If any comparison result in True, the program shall display the integer.
Based on this idea, an if-else condition is defined (Line 2). Outer loop will traverse through the shorter array (Line 3, 12) and the inner loop will traverse the longer array (Line 4, 13). Within the inner loop, there is another if condition to check if the current value is equal to any value in the longer array, if so, print the common value (Line 5-7, 14-16).
Following are the code in java to reverse any string without using reverse function.
import java.util.*; // import package
class Main // class
{
public static void main(String args[]) // main class in java
{
String s, r = ""; // string variable
Scanner out = new Scanner(System.in); // scanner classes to take input
System.out.println("Enter a string to reverse");
s = out.nextLine(); // input string
int l1 = s.length(); // finding length of string
l1=l1-1;
for ( int i = l1 ; i >= 0 ; i-- ) // for loop to reverse any string
{
r = r + s.charAt(i);
}
System.out.println(" The Reverse String is: "+r); // print reverse string
}
}
Explanation:
firstly we input any string ,finding the length of that string then after that iterating over the loop by using for loop and last display that reverse string
output
Enter a string to reverse
san ran
The Reverse String is: nar nas
