После долгой ночи программирования я, наконец, получил программу, которая распечатывает режим/режимы массива. Или даже сообщит вам, если режима нет (скажем, если ни один ввод не произошел более одного раза или все вводы произошли одинаковое количество раз: например, 1, 1, 2, 2, 3, 3, 4, 4 ). Некоторые ограничения программы заключаются в том, что вы должны ввести более одного числа, и вы не можете ввести более 10000 чисел или отрицательное число (если вы хотите ввести отрицательное число, вам просто нужно настроить все циклы for, включающие значения [][] Массив. Некоторые интересные вещи в моей программе заключаются в том, что она распечатывает, сколько раз каждый из вас вводил данные вместе с режимом вашего массива. И все распечатки грамматики меняются в зависимости от количества информации (пример. Режим вашего массива 2. Режимы вашего массива 1 и 2. Режимы вашего массива 0, 2, 5 и 8. В программе также есть пример функции пузырьковой сортировки для тех, кто думал, что им нужна была функция сортировки в их программе режима. Надеюсь, это поможет, я включил много псевдокода, чтобы помочь всем, кто не видит, как моя логика продвигается по всей программе (к вашему сведению: это Java, и он был скомпилирован в BlueJ).
