How do you find the sum of the digits in an array?

Declare a function, sumOfDigits() to calculate the sum of digits of a number. Traverse the array arr[] and for each array element, check if the sum of digits is equal to K or not. If found to be true, then increment count by 1. Print the value of count as the required answer.

How do you sum a list in Python?

Approach :

1. Read input number asking for length of the list using input() or raw_input() .
2. Initialise an empty list lst = [] .
3. Read each number using a for loop .
4. In the for loop append each number to the list.
5. Now we use predefined function sum() to find the sum of all the elements in a list.
6. Print the result.

What is the sum of 100 integers in a for loop?

Enter a positive integer: 100 Sum = 5050. In both programs, the loop is iterated n number of times. And, in each iteration, the value of i is added to sum and i is incremented by 1. Though both programs are technically correct, it is better to use for loop in this case. It’s because the number of iteration is known.

How to compute the sum of natural numbers from 1 to N?

To compute the sum of natural numbers from 1 to n (entered by the user), loops can be used. You will learn how to use for loop and while loop to solve this problem. The positive numbers 1, 2, 3… are known as natural numbers. The programs below takes a positive integer (let say n) as an input from the user and calculates the sum up to n.
