时间复杂度为O(n)，效率较低。所以ArrayList不适合做任意位置插入和删除比较多的场景。因此，java集合中又引入了LinkList，即链表结构。
5. 测试修正后的代码以确保异常不再出现 运行修正后的代码,确保没有 ClassCastException 异常抛出。如果代码逻辑正确,并且类型匹配,异常将不会再次出现。 通过以上步骤,我们可以有效地解决 java.lang.ClassCastException: insertion of illegal element: 30 异常,并确保代码的健壮性和正确性。
Insertion sortworks by comparing values at index with all its prior elements.We place value at the index where there are no lesser value to the elements. So when you reach last element,we get a sorted array. Lets see how it works: Lets say you have array as{100,20,15,30,5,75} Com...
In both the implementations, we can see that we begin sorting from the 2ndelement of the array (loop variable j = 1) and repeatedly compare the current element to all its previous elements and then sort the element to place it in its correct position if the current element is not in ord...
Insertion Sort is used to sort the list of elements by selecting one element at a time. It starts the sorting by choosing the first element from the unsorted array and placing it in the proper position of the sorted array. It will keep on doing this until the list of elements is fully...
Vector(Collection c): this constructor was added in vectors after the release of Java 2. This type of constructor creates a vector that contains the element of another collection c. NOTE: Once the initial capacity limit is reached, the size of the vector increases after each reallocation cycle...
Java C C++ # Insertion sort in PythondefinsertionSort(array):forstepinrange(1, len(array)): key = array[step] j = step -1# Compare key with each element on the left of it until an element smaller than it is found# For descending order, change key<array[j] to key>array[j].while...
The working of the insertion sort is mentioned below:We will select the first element and assume it is sorted in the array. Let's name this element as elementA. Compare the next element with the elementA.If the second element is less than the elementA then place the second element in the...

In the inner while loop, in starts at out and moves left, until either temp is smaller than the array element there, or it can't go left any further. Each pass through the while loop shifts another sorted element one space right. It may be hard to see the relation between the steps...
