Draw this triangle [CHALLANGE]

/*Using loops and ternary create this pattern. . ... ...... .......... --------------- --------------------- --------------- .......... ...... ... . Each loop adds all the previous loops upto 7 then does the same in reverse by subtracting. The one who creates this with the least amount of loops wins and gets a ✅. ☺ Reference guide 0 = 0 0+1 = 1 0+1+2 = 3 0+1+2+3 = 6 0+1+2+3+4 = 10 0+1+2+3+4+5 = 15 0+1+2+3+4+5+6 = 21 0+1+2+3+4+5 = 15 0+1+2+3+4 = 10 0+1+2+3 = 6 0+1+2 = 3 0+1 = 1 0 = 0 */

I may have gone a bit overboard condensing the code so I write this too :) https://code.sololearn.com/cQbf68JWJ2r7/?ref=app

Thanks for trying this guys i hope you liked my very difficult decision 😰 i thought i would use simplicity over complexity to help me make this decision as they were all amazing and id tick them all if i could but i just wanted to choose one that was the closest to what i expected and i feel like @David Ashton had the upper edge. This decision had nothing to do with us having the same first name by the way haha 😜 Thank you all keep being amazing!

n, k = 7, [] for i in range(2*n-1): if i < n: k.append(i+1) else: del k[-1] print('#'*sum(k))

One loop in java https://code.sololearn.com/cyfKl45f5kEg/#java Woops! I didn't initially notice that some lines were dots, not dashes! I have made the necessary changes.
