Answer: '' (An empty string)
Explanation:
Normally, when we are getting a substring, we will start from the character at index m and go until, but exclude the character at index n.
If m is greater than n, then we cannot get any substring as we would have to go backwards when we need to go forwards. If m=n, then we still cannot get any characters as we have to exclude the character at index n, making us have to exclude the character at index m as well.
Hence, for both situations the value would be an empty string, or a string with length 0.

In which disclosure paradigm will dislosure potentially help both the attacker and defender?
Information sharing is a disclosure paradigm in which disclosure will potentially help both the attacker and defender.
What is vulnerability?Vulnerability can be defined as any form of weakness, flaw or defect that is found in a software application, computer system, or network, which can be exploited by an attacker or a hacker, in order to gain an unauthorized access and privileges to sensitive user data that are stored in a computer system.
What is vulnerability disclosure?Vulnerability disclosure can be defined as a practice that typically involves reporting any security flaw in an equipment, computer software, or hardware, so as to avert and mitigate a potential attack (threat).
The types of disclosure paradigm.In Computer technology, there are four (4) main types of disclosure paradigm and these include the following:
Military: disclosure doesn't help the defender (low) but helps the attacker (high).Open source: disclosure helps the defender (high) but not the attacker (low).Information sharing: disclosure helps both the defender (high) and the attacker (high).Public domain: disclosure neither helps the defender (low) nor the attacker (low).In this context, we can infer and logically deduce that the information sharing is a disclosure paradigm in which disclosure will potentially help both the attacker and defender such as when the CIA or FBI considers whether or not to share a sensitive information with officials in other agencies.
