The attached dataset represent an individual interaction network among a set of students, teachers, and staff in a regular school day. The data was collected using a set of sensors that everyone in the school wore for a day, and an interaction was recorded when any given two sensors are closer than 1 meter from each other. Each line in the network.csv file contains the ID of the two individuals and a number representing the duration through which the two individuals were in close proximity. Each line in the people.csv has the node ID and its type (student, teacher, staff, other).Using ICM, please identify the most critical set of individuals which can cause the widest spread of COVID-19 in the school if they get infected based on their interaction pattern. Analyze and comment on the type of individuals included in this set. wwttiittee ppyytthhoonnee ccooddee
