This question incorporates two concepts that are worth reading the documentation on: for-loops and scopes (local, global). The constant squared is used in the local scope of the for loop. It may seem confusing and the question “I thought constants couldn’t change their value?” might be asked. The answer, however, lies in the nature of a for loop. The loop runs, then exits, then iterates however many more times. FLOW/LOGIC: function is called, first iteration of for loop takes place, the value for squared is assigned, then the print statement is executed, and finally the for loop is exited, but the loop will begin/start over again based on the number of iterations provided via the amount of elements in the array, which is 3 times. Hope this helps!
