Cyber Threat Analysis You are tasked with analyzing network data to identify potential cyber threats. You receive a dataset with timestamps of suspicious activities on a network. Your task is to determine the frequency of attacks. Given the following timestamps of attacks in a $24-$hour period:

Calculate the average time gap between these attacks.

Hint: First, convert the timestamps into a common unit, such as minutes. For example, $02$:$15$ AM $=2*60+15=135$ minutes, and $09$:$30$ AM $=9*60+30=570$ minutes. Then, calculate time gaps. For example, Gap $1=570-135=435$ minutes. Finally, compute the Average Gap $=($Gap $1+$ Gap $2+$ Gap $3+$ Gap $4)/4.$
