As you see, I got a runtime error because of "assert" function that I added while debugging my code. My array S is an array of pairs where second value is an index from (1..m). I can not understrand why my code is getting a runtime error. "assert(s[i].second <= m)" should be fine but it leads to an error. Why?

Look at the size of array a.

What is the undefined behavior of C++ here? The title is purely misleading.

    Well, he is looking for an index in array, which doesn't exist. This leads to undefined behavior, doesn't it?
