The H/R depаrtment оf а lаrge, multi-natiоnal cоmpany is attempting to create a numbering scheme for employee ID’s. They do not want to use the employee’s social security number for privacy reasons. In order to have enough possible unique combinations, the department has decided that the employee ID will be: First name initial, last name initial, last four of SSN, and the last two digits to indicate the employee’s assigned department number.

Which method(s) of coding did the H/R department utilize to create this numbering scheme? I. Mnemonic II. Block/Group III. Sequence
