answer of 6th question is 720 bcz n<7 not <= 7

Answer is 5040. Try it again step by step. When i becomes 6: the condition will become 6<7 So, the condition is true that means i become i+1 (i.e., i = 7) Now, X = x*i (i.e., X = 720*7=5040) Again we have to check condition which is 7<7 (False) So, we came out of the loop and print(x) which is 5040.

Hope you got it. Try it once 🙂
