 * @description
 * CWE: 190 Integer Overflow
 * BadSource: console_readLine Read data from the console using readLine
 * GoodSource: A hardcoded non-zero, non-min, non-max, even number
 * Sinks: square
 *    GoodSink: Ensure there will not be an overflow before squaring data
 *    BadSink : Square data, which can lead to overflow
 * Flow Variant: 51 Data flow: data passed as an argument from one function to another in different classes in the same package
