数组分为静态数组和动态数组: 静态(static):每个item占据相同宽度的内存位置。其支持的语言比如Java。 动态(dynamic):每个item占据的内存位置要比所需的多,通常是所需的两倍。其支持的语言比如Python。 python实现:直接用list实现,例如:a=[1, 2, 3, 4]。 时间复杂度(Time Complexity): initialize(初始化操作):...
在 Java 中,JDK 1.2 中定義了一個名為 “Collection Framework” 的單獨框架,它包含所有集合類和接口。集合分為兩部分,排序集和未排序集機器人各有優缺點。 Sorted Set 即 TreeSet 對其唯一元素進行排序,但 TreeSet 的 time-complexity 為 O(N log N),但未排序的 Set(如 HashSet 和 LinkedSet)確實改變了...
初学者可以尝试自己实现 std::array 功能，而不是像看 Java 面试题一样，仅仅背诵 String、 StringBuff...
This is a very useful and frequently used operation in Java. It is also a top voted question on Stack Overflow. As shown in top voted answers, this can be done in several different ways, but the time complexity could be very different. In the following I will show the time cost of ea...
The time complexity of this algorithm is O(n/2) which is O(N) because we are iterating over array till midpoint only. This should be your solution on interviews, the rest of the two methods are for practical use purposes. Btw, if you are preparing for Java interviews and solving codin...
Given an array of integers nums sorted in ascending order, find the starting and ending position of a given target value.If target is not found in the array, return [-1, -1].Follow up: Could you write an algorithm with O(log n) runtime complexity?
Why is processing a sorted array faster than processing an unsorted array in Java?Processing a sorted array can be faster than processing an unsorted array because certain algorithms and operations have a lower average time complexity when the input is already sorted. For example, the time...

The time complexity of the recursive approach to find the maximum and minimum values in a Java array is O(log n). However, it’s important to consider potential performance issues for large arrays due to the recursive calls and stack space required....
