While the below code working :-
m = {:a => 2, :b => 3,:c => 44,:g => 14}
a = [:a,:b,:g]
p m.values_at(*[:a,:b,:g]) #=> [2, 3, 14]
why the below not working?
h = {
''arg0'' => ''126150656000'',
''arg1'' => ''Intel(R) Core(TM) i7-2640M CPU @
2.80GHz'',
''arg2'' => ''2790'',
''arg3'' => ''3276320768'',
''arg4'' => ''8467496960'',
''arg5'' => ''Windows 7'',
''arg7'' => ''amd64'',
''arg6'' => ''6.1'',
''arg8'' => ''2'',
''arg9'' => ''1920'',
''arg10'' => ''1200'',
''arg11'' => ''32'',
}
p ar = h.keys.sort_by{|s| s[3..-1].to_i}
p h.values_at[*ar]
#=>`[]'': wrong number of arguments (12 for 1..2) (ArgumentError)
Where did I mistake?
