In this section, we are going to see how to reverse a number using various methods like while loop, recursion, for loop and do while loop with the help of examples. Example 1: Find Reverse Number in C++ Using While Loop Before moving to the program, let’s first understand how while l...
While Loop Program to Reverse the Digits of a Number in Python #Functionto reverse a given numberdefrev_num_while_loop(num):rev_no=0whilenum>0:# Extract the final digitlast_digit=num%10# Add the final digit to the reversed numberrev_no=(rev_no*10)+last_digit# Remove the final digit...
whileidx>=0:newList.append(numbers[idx])idx=idx-1print(newList) Output: [52, 44, 105, 34, 17, 97, 45, 2, 78, 66] Reverse a List Using the Slice Operator in Python If you prefer not to loop over the list, then use thesliceoperatorto decrement the array index by 1. ...
Python Code: # Define a function named 'string_reverse' that takes a string 'str1' as inputdefstring_reverse(str1):# Initialize an empty string 'rstr1' to store the reversed stringrstr1=''# Calculate the length of the input string 'str1'index=len(str1)# Execute a while loop until...

#Python Example: Reversing a list with slicingnumbers=[1,2,3,4,5]reversed_numbers=numbers[::-1]print(reversed_numbers)# Output: [5, 4, 3, 2, 1]print(numbers)# Original list remains [1, 2, 3, 4, 5] Here,reversed_numbersis a new list containing the elements ofnumbersin reverse ...
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. Finally, the reversed string is created using the String constructor and displayed. Reverse a...
Traverse a Python list in reverse order: In this tutorial, we will learn how to iterate/traverse a given Python list in reverse order using multiple approaches and examples.
forEach { number in print("Number is \(number)") } Output Number is 10 Number is 9 Number is 8 Number is 7 Number is 6 Number is 5 Number is 4 Number is 3 Number is 2 Number is 1 Using a for Loop with the Indices Property of an Array You can reverse the indices of the...
Original string: Python Reverse string: nohtyP Flowchart: For more Practice: Solve these Related Problems: Write a C++ program that reverses a string using recursion without any library functions. Write a C++ program to reverse a string by swapping its characters in-place using two pointers. ...
