//Write a program that receives some info from the console about people and their phone numbers.
//You are free to choose the manner in which the data is entered; each entry should have just one name and one number
//(both of them strings).
//After filling this simple phonebook, upon receiving the command "search", your program should be able to perform
//a search of a contact by name and print her details in format "{name} -> {number}". In case the contact isn't found, print
//"Contact {name} does not exist."
