Akash Gupta length is 9 because we are appending in original array. Explaination: a = [1, 2, 3, 4, 12, 13] According to condition 1 % 2 == 1 //true Now a will be a [1, 2, 3, 4, 12, 13, 0] 3 % 2 == 1 //true Now a will be a [1, 2, 3, 4, 12, 13, 0, 0] 13 % 2 == 1 //true Now a will be a [1, 2, 3, 4, 12, 13, 0, 0, 0] Finally length will be 9 see here.. https://code.sololearn.com/cGydxwaIInsV/?ref=app

To add to Abhay 's answer: for the output to just be 9, the if should be if i%2 != 0, and print should be de-indented. Length of a starts out at 6 and, for every odd number (assuming the 'if' is amended as above), a 0 is added to it. As this happens 3 times, len(a) is 9 at the end.

Show me your Code.

Akash Gupta In your post and in this question condition is different. Why?

+6

Akash Gupta I already solved with explaination.

AJ Anant - C#/Java Challenger Got it .....✌️✌️

It doesn't gives any indentation errors ,perhaps the error maybe about print since it is lowercase not uppercase Also the output is 6 7 7 8 9 9 10 11 12 . . infinite Which is right.

+5

Akash Gupta According to your code you are printing the length inside loop that's why you are getting output like that.

𝐊𝐢𝐢𝐛𝐨 𝐆𝐡𝐚𝐲𝐚𝐥 andAJ Anant - C#/Java Challenger thanks for the help ......

Ishu Kumar There is no difference. No need to update question. In description he also mentioned why the output 9.

Akash Gupta Please double check the code in the challenge. This code will not give 9. If this is what the code says, report question for having wrong answer.

𝐊𝐢𝐢𝐛𝐨 𝐆𝐡𝐚𝐲𝐚𝐥 We each had a different guess and both were wrong! 😆

Akash Gupta My explanation above is still correct...

I believe the correct answer is AJ Anant . If its remainder 1(odd number), append 0 to the original list (not the number). From the list 3 of the numbers are odd so three zeros are added to the original list. Length of list would be 9 not infinity. Would only be infinity if the original numbers which are odd are added back.

Be cause you are printing length of the list and also appending 0 when the elements of the list give a remainder of 1 when divided by 2 . And there are three cases when the remainder is 1 when the elements of the list is divided by 2 i.e. 1, 3, 13 . That's why 0 has been appended 3 times in ur list and ur resultant list looks like [1,2,3,4,12,13,0,0,0] You can easily count that there are 9 elements in the list . That's why the result is 9 . Hoping that u will understand . If the issue remains unsolved kindly message me .

𝐊𝐢𝐢𝐛𝐨 𝐆𝐡𝐚𝐲𝐚𝐥 Yeah, either way works!
