hi! could you please explain what the lp variable is for? (lp=-1) thanks again for creating these videos!

[@codingcart]

Hi Danielle,
Initially I have declared lp for assigning the latest picked value but this was taken care by "latest" variable in while loop so it was unused.
Hope this helps😊

[@ddaanniieellllee]

[@AbhishekKumar-ob7vh]

Nice explanation 👌

[@codingcart]

Thank you 🙂

[@akshaypatil9663]

you haven't done any checks for the constraints defined in the problem

[@charan6788]

Why did you use latest value
When every value piles up when it is less than csv and then latest value would surely less than csv . But when i did the program without latest but it didn't get the answer.u could have explained it moee

[@dianacampbell6336]

3:54 But you can use 4, 4, 3, 3, 2, 1 ?

[@kushaldas8496]

Sir, can you please make a videos on classes module from hackerrank please sir. :)

[@codingcart]

stay tuned you will be notified.

[@balavighnesh5843]

hloo as the list contains the number of elements entered by the user ie" n ' but you didnt took any loop for that why?

[@codingcart]

Coz here we are taking the input as a string and then mapping it to int

[@Sumitsingh-ey5zb]

what is lp = -1 ........can u explain here?

[@codingcart]

Hi Sumit,
Initially I have declared lp for assigning the latest picked value but this was taken care by "latest" variable in while loop so it was unused.
