Question

def tri_recursion(k):
if(k > 0):
result = k + tri_recursion(k - 1)
print(result)
else:
result = 0
return result

print("\n\nRecursion Example Results")
tri_recursion(6)

Answer 1

Given a value k, if k is greater than 0 print k + the result of tri_recursion(k -1).

Let k = 3
K > 0
Result = 3 + 5 (k-1 -> 2 + k -> 5)
Result = 8

Answer 2
