Line 4:
Using a straightforward longhand loop as in the JavaScript and Phix examples below, show the locations of elements which are identical to the immediately preceding element in {1,2,2,3,4,4,5}. The (non-blank) results may be 2,5 for zero-based or 3,6 if one-based. <br>
The purpose is to determine whether variable declaration (in block scope) resets the contents on every iteration.<br>
There is no particular judgement of right or wrong here, just a straightforward statement of subtle differences.<br>
If your programming language does not support block scope (eg assembly) it should be omitted from this task.
