add n/1 p/98765432 e/[email protected] a/John street, block 123, #01-01

add n/2 p/98765432 e/[email protected] a/John street, block 123, #01-01

delete 2

Possible solution suggestion:

• Maybe can restrict the names to not allow pure numerals so 15 will not be a valid name
• Can limit the usage of assign to only use index
• Can note that if value passed in is numerical, will be considered as index in the userguide
• Inform the user that there is a contact with the name that is also a index
