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.
