Pruthvi Patel

This is different than previous uploaded question please see carefully.

I have one array called ans[i].

ans[i]={1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 } //n no.of inputed element.

and i want to split in group of 3 and sum of 3-3 elements and stored it in array.Like this

res[0]= 35 //1+4+7+10+13

res[1]=40 //2+5+8+11+14

res[2]=45 //3+6+9+12+15....like this.

Hi,
You can try below code for the same-
int[] ans = new int[] { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15 ,16,17};
int[] res = new int[3] { 0, 0, 0 };
int cnt = 0;
for (int i = 0; i < ans.Length; i++)
{
if ((i % 3) == 0)
{
res[0] += ans[i];
}
else
{
if (cnt == 0)
{
res[1] += ans[i];
cnt = 1;
}
else
{
res[2] += ans[i];
cnt = 0;
}
}
}
Just out of curiosity, may I know why do you require this kind of codes?
