Надеюсь среднюю разницу возрастов сам сможешь посчитать?

ksa 22.12.2017 16:02
IAmTrying, но в твоем примере нет данных по некоторым матерям...
Например Livina de Vrieze. Есть трое ее детей, а по ней инфы нет. :no:
Т.ч. придется делать защиту на вычисление "средней разницы" возрастов.

IAmTrying 22.12.2017 16:13
Да, смогу) спасибо большое)

IAmTrying,
Пожалуйста, отформатируйте свой код!

Для этого его можно заключить в специальные теги: js/css/html и т.п., например:
[js]
... ваш код...
[/js]


О том, как вставить в сообщение исполняемый javascript и html-код, а также о дополнительных возможностях форматирования - читайте http://javascript.ru/formatting.

IAmTrying 22.12.2017 22:33
Отформатировал, извиняюсь) Если не трудно оцените код, и расскажите об изъянах, буду очень благодарен..
