# Find the length of the array and store it in n n = len(arr) findIndexOfMaxElement(arr, n) 现在,我们在 Python 中编译上述代码,编译成功后运行它。输出结果如下 5 is the element with maximum frequency, which is present at index: 11 结论
To find the index of the maximum element in an array, we usethenumpy.argmax()function. This function works with a list and can return the index of the maximum element. Example: importnumpyasnp lst=[1,4,8,9,-1]i=np.argmax(lst)print(i) ...

Example 2: Max & Min of Columns in NumPy ArrayExample 2 shows how to find the max and min values of a NumPy array by columns.For this task, we have to set the axis argument to be equal to 0:print(np.max(my_array, axis = 0)) # Get max of array columns # [4 5 6]...

In this introduction to NumPy, you'll learn how to find extreme values using the max() and maximum() functions. This includes finding the maximum element in an array or along a given axis of an array, as well as comparing two arrays to find the larger el
方法一:np.max()函数 + np.where()函数 如下图所示,x是一个 3×3 的二维np.array,首先使用np.max(x)求出x中的最大值,然后使用np.where函数找出数组x中最大值所在的位置。当然这只是np.where的其中一种用法,np.where是一个非常方便的函数,用法还有很多,具体可自行阅读官方文档。
1.2 算法的心脏:详解merge操作 (The Heart of the Algorithm: A Detailed Explanation of themergeOperation) 如果说归并排序是一部精密的机器,那么merge函数就是驱动这部机器运转的引擎。理解了merge,就理解了归并排序的半壁江山。 merge操作的目标非常明确:输入两个已经排好序的数组(或子数组),输出一个包含了这两...
