# Phone directory
# John keeps a backup of his old personal phone book as a text file.
# On each line of the file he can find the phone number (formated as +X-abc-def-ghij
# where X stands for one or two digits), the corresponding name between < and > and the address.

# Unfortunately everything is mixed, things are not always in the same order;
# parts of lines are cluttered with non-alpha-numeric characters (except inside phone number and name).

# Examples of John's phone book lines:
# "/+1-541-754-3010 156 Alphand_St. <J Steeve>\n"
# " 133, Green, Rd. <E Kustur> NY-56423 ;+1-541-914-3010!\n"
# "<Anastasia> +48-421-674-8974 Via Quirinal Roma\n"
# Could you help John with a program that, given the lines of his phone book and a phone number
# returns a string for this number : "Phone => num, Name => name, Address => adress"

# Examples:
# s = "/+1-541-754-3010 156 Alphand_St. <J Steeve>\n 133, Green, Rd. <E Kustur> NY-56423 ;+1-541-914-3010!\n"

# phone(s, "1-541-754-3010") should return "Phone => 1-541-754-3010, Name => J Steeve, Address => 156 Alphand St."
# It can happen that, for a few phone numbers, there are many people for a phone number -say nb- , then
# return : "Error => Too many people: nb"

# or it can happen that the number nb is not in the phone book, in that case
# return: "Error => Not found: nb"

# You can see other examples in the test cases.

# Codewars stdout doesn't print part of a string when between < and >
