Школьники в библиотеке

[glorius_May]

On Monday a school library was attended by 5 students, on Tuesday, by 6, on Wednesday, by 4, on Thursday, by 8, and on Friday, by 7. None of them have attended the library two days running. What is the least possible number of students who visited the library during a week?

А как понять "two days running"? Это два дня подряд?

Никто из них не посещал библиотеку в течение двух дней на бегу.

Но вообще два дня подряд, конечно.
