EASYLoops

Read 4 stock counts, one at a time. Each count must be validated so that only values from 0 to 999 (inclusive) are accepted — reject and re-ask for anything outside that range. Output the total of the 4 valid counts.

Input: Stock count entries (some may be invalid and re-entered) until 4 valid values have been read. Output: Total stock: <total>.

Example:

Input:  10
        20
        30
        40
Output: Total stock: 100

Premium is coming soon. All grading features are currently unlocked.
