Python Program to Swap the First and Last Value of a List
- Take the number of elements in the list and store it in a variable.
- Accept the values into the list using a for loop and insert them into the list.
- Using a temporary variable, switch the first and last element in the list.
- Print the newly formed list.
- Exit.
How do you return the first digit of an integer?
To finding first digit of a number is little expensive than last digit. To find first digit of a number we divide the given number by 10 until number is greater than 10. At the end we are left with the first digit.
How do you change a 2 digit number?

How do I change the first and last digit in C++?
Write C++ program to swap first and last digit of a number
- #include
- {
- int num, last, first, temp, swap, count = 0;
- //Reading a number from user.
- cout<<“Enter any number:”;
- cin>>num;
- temp = num;
- last = temp % 10;
How do you swap digits in Python?
Maximum Swap in Python
- num := cut each digit from the number, and make a list.
- num1 := sort the num in reverse order.
- index := 0.
- while index < length of num. if num1[index] is not same as num[index]
- join the numbers present in num and make this as integer.
- return the result.
How do you find the second digit of a number?
You can do it by dividing by ten and then taking the remainder of division by ten: int second = (number / 10) % 10; In general, you could think of integer-dividing by a k -th power of ten as of dropping k least significant digits.
How do you convert to int?
Java int to String Example using Integer. toString()
- public class IntToStringExample2{
- public static void main(String args[]){
- int i=200;
- String s=Integer.toString(i);
- System.out.println(i+100);//300 because + is binary plus operator.
- System.out.println(s+100);//200100 because + is string concatenation operator.
- }}
How do you swap digits?
Algorithm to swap first and last digit of a number:
- Ask the user to enter an integer number. Suppose n = 12345, where n is an integer variable.
- To find the last digit of a number, we use modulo operator %.
- Find the first digit with the help of mathematical operation.
- Use below logic to swap first and the last digit.
How do you interchange numbers?
That is, to interchange, it must be a two-digit or more than two-digit number. If the given number is a two-digit number, then simply reverse the number. For example, if the number is 12 then after reversing, it will become 21. See, its digit (first and last) gets interchanged.
How do you convert digits to integers in python?
Take this number, 532, exchange the first and last digits to get 235. Now subtract 235 (the smaller of the two numbers) from 532 (the larger of the two numbers), and the result is 297. Take the difference, 297, and switch its first and third digits to get 792. Add 297 to 792, and the result is 1089.
How do you find the length of a list without Len?
How to implement without using len():
- Take input and pass the string/list into a function which return its length.
- Initialize a count variable to 0, this count variable count character in the string.
- Run a loop till length if the string and increment count by 1.
