The sum of an odd number and an even number can be expressed as (2n+1)+(2m), where n and m are integers. (2n+1 must be odd, and 2m must be even.) Their sum is equal to 2n+2m+1, or 2(m +n)+ 1. Since (m+ n) is an integer, the quantity 2(m +n)+1must repr...
Write a program to input an integer N and print the sum of all its even digits and sum of all its odd digits separately. Digits mean numbers, not the places! That is, if the given integer is "13245", even digits are 2 & 4 and odd digits are 1, 3 & 5. ...
The sum of odd numbers from 1 to 9 = 1 + 3 + 5 + 7 + 9 (5 numbers) = 25 = 52 The sum of odd numbers from 1 to 11 = 1 + 3 + 5 + 7 + 9 + 11 (6 numbers) = 36 = 62By the above observation, we can derive a formula that "the sum of first n odd numbers is ...
Intuition and AlgorithmLet's try to maintain S, the sum of the array throughout one query operation.When acting on an array element A[index], the rest of the values of A remain the same. Let's remove A[index] from S if it is even, then add A[index] + val back (if it is ...
