так что я создаю бронирование авиабилетов, но после повторной попытки места, которые я впервые выбрал, не могут прочитать в результатах
пример
ABC DEF
1 xxx xXx
2 xxx xxx
я выбираю место 1E и после использования tryснова и выберите 2А, это станет таким
ABC DEF
1 xxx xxx
2 Xxx xxx
не
ABC DEF
1 xxx xXx
2 Xxx xxx
Может ли кто-нибудь помочь мне, мой профессор не учил так много, я просто исследую сам, если у меня есть свободное время
