Hash#shift() is a Hash class method which removes a key-value pair from hash and then it returns these value as two-item array.
Syntax: Hash.shift()
Parameter: Hash values
Return: two-item [key-value] array
Example #1 :
# Ruby code for Hash.shift() method # declaring Hash value a = {a: 455 , b: 200 }
# declaring Hash value b = {e: 500 , c: 300 , b: 200 }
# declaring Hash value c = {a: 100 }
# shift Value puts "Hash a shift form : #{a.shift()}\n\n"
puts "Hash b shift form : #{b.shift()}\n\n"
puts "Hash c shift form : #{c.shift()}\n\n"
|
Output :
Hash a shift form : [:a, 455] Hash b shift form : [:e, 500] Hash c shift form : [:a, 100]
Example #2 :
# Ruby code for Hash.shift() method # declaring Hash value a = { "a" => 344 , "b" => 200 }
# declaring Hash value b = { "a" => 100 }
# declaring Hash value c = { "e" => 100 , "c" => 300 , "b" => 200 }
# shift Value puts "Hash a shift form : #{a.shift()}\n\n"
puts "Hash b shift form : #{b.shift()}\n\n"
puts "Hash c shift form : #{c.shift()}\n\n"

Output :
Hash a shift form : ["a", 344] Hash b shift form : ["a", 100] Hash c shift form : ["e", 100]
