How can I find an array index based on a match from a second array?

How can I find the index of an element in one array based on a match from a second array?

To find the index of an element in one array based on a match from a second array, you can follow these general steps:

Steps: Iterate Through the First Array: Loop through each element of the first array.

Check for Matches: For each element in the first array, check if it exists in the second array.

Record the Index: If a match is found, record the index of the element from the first array.

Practical Example: Imagine you have two arrays:

array1: [10, 20, 30, 40, 50]

array2: [30, 50, 10]

To find the indices of elements in array1 that match with elements in array2, you would:

Loop through array1.

Check if each element in array1 is present in array2.

Record the indices of matching elements.

Result: For the given arrays, the indices of array1 elements that match with array2 would be [0, 2, 4] (corresponding to elements 10, 30, 50).

By following these steps, you can efficiently find the indices of matching elements between two arrays.
