I was taught not to write things like a=a+++++a.

However I love writing a++ because I believe that it always gets executed after a whole sentence (perhaps, right after a , or ;?)

But today I wrote this and got WA:

if(hh < tt && a[hh+1] == a[hh]-1) c[hh+1] += 2*c[hh++];

wa code: 154812779

rewrote it like this and got AC:

if(hh < tt && a[hh+1] == a[hh]-1) c[hh+1] += 2*c[hh], hh++;

ac code: 154812722

I'm wondering if it's wrong somewhere else or am I misunderstanding the usage of x++?
