Problem 3: Triangular numbers Use a for loop to compute the 10th triangular number. The nth triangular number is defined as 1+2+3+...+n. (You can also compute the nth triangular number as n"(n+1)/2. Use this formula to double-check that your loop is correct.) Hint: This outline is an almost-complete solution. You only have to replace each ellipsis by an expression. n - 10 triangular -0 for i in ... triangular print("Triangular number", n, "via loop:", triangular) print("Triangular number", n, "via formula:", n. (n + 1) / 2) Your code should be able to correctly calculate the 11th, 12th, or any other triangular number just by changing the first line to set n to 11, 12, or any other number. Be sure the code you submit calculates the triangle number forn - 10. Using the range function should help you accomplish this
