 # how do I solve this pattern? I'm able to do the left half, but can't think of the right logic for the right half. Anyone wants to help?

1 2 3 4 5 26 27 28 29 30
6 7 8 9 22 23 24 25
10 11 12 19 20 21
13 14 17 18
15 16

you should calculate what is the number of numbers below any level, int this case it’s (n*(n+1)) and then after reaching the end of current counter you should add that much to your current value .

//Hey ! try my code this will work and please adjust spaces if u want in that code :)…

Here’s the code I wrote but the right half isn’t the expected oucome…

``````#include<stdio.h>
int main()
{
int x=1,y=30,n=10,r,s,c;
for(r=1;r<=n;r++)
{
for(s=2;s<=r;s++)
{printf(" ");}
for(c=5;c>=r;c--)
{printf("%d\t",x);
x++;}
for(s=2;s<=r;s++)
{printf(" ");}
for(c=5;c>=r;c--)
{printf("%d\t",y);
y--;}
printf("\n");
}
}``````
