Hello Codeforces,
In Round #819 (Div. 1 + Div. 2) today, my solution for problem A turns out it was wrong after the updated tests.
So my first solution was with the picture where b ==> int b=*max_element(arr+1,arr+n);
but after the contest finished i submitted a new solution where b ==> the one with picture where i used a loop.
the first solution failed on test #4, and the second was accepted.
But i really don't understand why the first solution was wrong, or why it didn't pass the updated tests.
Any help!! Thank you all.








notice that n could probably be 1 so your code should run
max_element(arr+1,arr+1)and it turns out like random value or something, idk.Yes, I tried it in c++ 14 compiler and gave me a large random value.
So yes probably that is the reason.
Thank you for your response.
