How do you find the first and last digit of a number?

How do you find the first and last digit of a number?

To find last digit of a number, we use modulo operator \%. When modulo divided by 10 returns its last digit. 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.

How do I find the first and last digit of a number in Python?

python program for sum of first and last digit of a number

1. n = int(input(“Enter any number : “))
2. number = str(n)
3. first = int(number[0])
4. last = int(number[-1])
5. print(f”sum of {first} and {last} is : “,sum)

How do you find the sum of the first and last digits in Java?

Step 1: Take a number from the user. Step 2: Create two variables firstDigit and lastDigit and initialize them by 0. Step 3: Use modulo operator( \% ) to find last digit. Step 5: Display the result.

How do you find the second last digit of a number?

Steps

1. Let N be the input number.
2. If N is a one-digit number, return -1.
3. Set N = N / 10. This step removes the last digit of N.
4. N \% 10 gives us the last digit of N. Since we have already removed the last digit of N in the previous step, N \% 10 is equal to the second last digit of the input number.
5. Return N \% 10.

How do you sum two digits in Python?

How to sum the digits of a number in Python

1. number = 123.
2. sum_of_digits = 0.
3. for digit in str(number): turn to string to iterate through.
4. sum_of_digits += int(digit)
5. print(sum_of_digits)

How do you find the position of a digit in a number?

Logic to Find N-th Digit of a Number

1. Do div operation with the number with 10N (num = num / pow (10, N)). The right most digit of the result would be the intended digit.
2. Do modulo operation on the result with 10 (num = num \% 10).

What are the last two digits of the number 76?

Therefore, our purpose is to get 76 as last two digits for even numbers. We know that ends in 76 and ends in 24. Also, 24 raised to an even power always ends with 76 and 24 raised to an odd power always ends with 24. Therefore, will end in 76 and will end in 24.

How to find first and last digit without using loop in C?

Logic to find first and last digit of a given number without using loop in C program. Before I explain logic to find first digit, let us first learn to find last digit of a number. To find last digit of a number in programming we use modulo operator \%. A number when modulo divided by 10 returns its last digit.

How to find the first and last digit of a number?

This program allows the user to enter any number. And then, it is going to find the First Digit and the Last Digit of the user-entered value. Within this Program to Find First and Last Digit Of a Number, Number = 1234 Count = log10 (Number) – This will return the total number of digits in a Number -1

How to find the first and last digit of 1234 using functions?

FirstDigit = 1234 / pow (10, 3) = 1234 / 1000 = 1.234 = 1 This program to find the first and last digit is the same as above, but this time we divided the code using the Functions concept. We have already explained the Analysis part in the previous articles.

How to find last digit using modulo division by 10?

Find last digit using modulo division by 10 i.e. lastDigit = num \% 10. To find first digit we have simple formula firstDigit = n / pow (10, digits – 1). Where digits is total number of digits in given number.
