Introduction: In the project, it is necessary to obtain the intersection of multiple arrays, so this example is only suitable for specific scenarios. For example, A array var a = {1000,10001,10002, 10003}; B array var b = {10002, 10003}; C array var c = {10003}; It is necessary to obtain the intersection array of these three arrays. The specific idea is: initialize one first. The smallest array is the A array, and the smallest number of elements is also the length of the array A. However...
