Step by Step solution about How to resolve the algorithm Pick random element step by step in the Julia programming language

The provided Julia code uses the rand function to generate a random element from the given array. Here's how it works:

1. array = [1,2,3]: This line creates an array with three elements: 1, 2, and 3.

2. rand(array): This line calls the rand function with the array as an argument. The rand function generates a random index within the specified range or array. In this case, it will generate a random index between 1 and 3, inclusive.

3. The generated random index is used to access the corresponding element from the array. For example, if the random index generated is 2, then the value 2 will be returned.

4. The returned value will be assigned to the variable that stores the result of the rand function call. In this case, the result is not assigned to any variable, so it will be printed to the console.

When you run this code, it will print a random element from the array [1,2,3]. The output will vary depending on the random index generated. For example, you might see an output like this:

2

This indicates that the random index generated was 2, and the corresponding element from the array was 2.

Note that the rand function is a generic function that can be used with different types of arrays and sequences. It can also be used to generate random numbers within a specified range using the rand(start, stop) syntax.

array = [1,2,3]
rand(array)
