方法A:使用StringBuilder publicStringreverseUsingStringBuilder(Stringstr){returnnewStringBuilder(str).reverse().toString();} 1. 2. 3. 方法B:使用循环 publicStringreverseUsingLoop(Stringstr){StringBuilderreversed=newStringBuilder();for(inti=str.length()-1;i>=0;i--){reversed.append(str.charAt(i));}...
Program 2: Reverse a number using for Loop The logic in this program is same as above program, here we are usingfor loopinstead of while loop. As you can see, in this program we have not used the initialization andincrement/decrementsection of for loop because we have already initialized ...
The input string "Java Program" is defined, and we convert it into a character array. Using a for loop, each character is pushed onto the stack. As the stack follows LIFO, popping elements from it will yield the characters in reverse order, which are stored in a new character array. ...
Let’s consider a simple example where we have an array of integers and we want to print them in reverse order using aforloop. publicclassReverseTraversal{publicstaticvoidmain(String[]args){int[]numbers={1,2,3,4,5};for(inti=numbers.length-1;i>=0;i--){System.out.println(numbers[i])...
3.6.2. Use integer variable to control the while loop 3.6.3. Check the loop counter for while loop 3.6.4. Use while loop to output all elements in an array 3.6.5. Use Do while loop to reverse a string 3.6.6. Nesting If statement to a while statement 3.6.7. Using While loop to ...
We can use a for loop to reverse the contents of a string variable. See the below example code. using System; namespace reverse_string { class Program { static string Reverse(string text) { char[] charArray = text.ToCharArray(); string reverse = String.Empty; for (int i = charArray....
An easy way to solve the problem is through simple iteration by just using a for loop with i from index 0 to n/2 and then character interchanging with n-i. But here, we will look into the solution of the problem using recursion. ...
Using the reversed() Method This method returns a new array by reversing the elements of an array. It does not change the order of the input array. Step 1 ? Create an input array to iterate Step 2 ? Perform a for loop with the reversed() function Step 3 ? Perform an action on each...
In natural language processing and parsing, searching for a string from end to start is often simpler. For debugging, a string reverse would be useful, or as an alternative way of writing the loop (reverse the string and then loop from index 0 to n-1). ...
