@J-B-Mugundh you should try this

[J-B-Mugundh]

@arjunatapadkar Okay sure.. please assign it to me!

[arjunatapadkar]

inside the page somewhere around code snippets there should be a "try it yourself" or similar button which should redirect to playground page

Okay!

[arjunatapadkar]

try this @AswaniBolisetti

[AswaniBolisetti]

@arjunatapadkar Could you please tell me why the page is in loading state only

[arjunatapadkar]

Checkout your internet connection It's working fine - Check it at live at codeteria.vercel.app/dsproblem

@arjunatapadkar In the live page, it is working but when i run the code and it is showing like that
