 * @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: multiply
 *    GoodSink: Ensure there will not be an overflow before multiplying data by 2
 *    BadSink : If data is positive, multiply by 2, which can cause an overflow
 * Flow Variant: 51 Data flow: data passed as an argument from one function to another in different classes in the same package
