Question 14 know 1 + 2 + 3 +... How much is + 99?
The inside of an array of add up the number 100, minus 1 + 2 + 3 +,,,, + 99, you get the results

Topic is simple but can be expanded to speak a little programming tip
There is a very common technique of an exclusive or operation
^ ^ b b==
^ the same number 2 times to get the result is itself
0 ^ a==a
So we can do it here
Define variables n initialized to 0
Then iterate over the array
Every time n ^ array elements at the same time ^ loop variables from 0 to 99
Eventually n is 2 times the number
