Question

input 1::: array of some integers("+ve or -ve")
input 2::: a positive integer 'n'

eg1--(task and outputs)-->
array= [1,3,4]
n=5
--1+3+4+1+3 = 12
--3+4+1+3+4=15
--4+1+3+4+1=13
output array= [12,15,13]

eg2--(task and outputs)-->
array= [1,6,7,8]
n=3
--1+6+7=14
--6+7+8=21
--7+8+1=16
--8+1+6=15
output array= [14,21,16,15]

eg3--(task and outputs)-->
array= [4,5]
n=5
--4+5+4+5+4=22
--5+4+5+4+5=23
output array= [22,23]

SAMPLE INPUT:
2 -4 6 -7
5
SAMPLE OUTPUT:
print the input
[ -1 , -7, 3, -10]

Answer 2

Here you go. Checks for valid input. Negatives come into play, but if they did, it would calculate correctly.

Answer 4

mine https://code.sololearn.com/WES8XsiH0sgQ/?ref=app

note: in the second example the sum of 8+1+6 is 15 ☺

note2: if you put the steps as array's length, the resultant array will have all the same terms

Answer 5

@ysraelcon Actually any number that is a multiple of input array's length will give the same result. Nice catch though 👍

Answer 11

Here's my C# implementation ✌

LINQ One-Liner〰
Enumerable.Range(0, len)
.Select(n =>
Enumerable.Range(n, count)
.Sum(i => numList[i % len]))

Once again, I must confess that I love LINQ so much. Enjoy!
