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...
In summary, Python provides a simple way to reverse a list by making use of the functionreversed(). You also can reverse a list manually by looping it in afororwhileloop. Python also has an easy method of reversing a list in a single line if you are comfortable using the slice operato...
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...
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...
Here,reversed_numbersis a new list containing the elements ofnumbersin reverse order, whilenumbersremains unchanged. Choosing the right technique In summary, usereverse()for in-place modifications when you don’t need the original list in its initial order.Use slicing ([::-1]) when you want ...

2. Using reversed() method You can also usereversed()method while iterating over the list elements. It returns a reverse iterator and it does not modify the given list. Example # Traverse a Python list in reverse order# Using reversed() method# Define a listlist1=[10,20,30,40,50]# ...
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 the reversed() Method with a Range You can define a range to iterate in a loop. Using the reversed() function, you can iterate the range in revers...
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...
{ WhileStatement(path) { // switch 节点 let switchNode = path.node.body.body[0]; // switch 语句内的控制流数组名,本例中是 _0x34e16a let arrayName = switchNode.discriminant.object.name; // 获得所有 while 前面的兄弟节点,本例中获取到的是声明两个变量的节点,即 const _0x34e16a 和 let...
