Given a string, such as "ABCD 100", what is the most efficient way to convert it into {"ABCD": 100}, where "ABCD" is the key and 100 is an integer and the value?
Assuming that you have more than one key-value pair, you can combine split, each_slice and map:
"ABCD 100 EFG 200".split
.each_slice(2)
.map {|k, v| [k.to_sym, v.to_i]}.to_h
#=> {:ABCD=>100, :EFG=>200}
Or with scan and groups:
"ABCD 100 EFG 200".scan(/([A-Z]+)\s([0-9]+)/)
.map! {|k, v| [k.to_sym, v.to_i]}.to_h
#=> {:ABCD=>100, :EFG=>200}
Use regex according to your actual issue, it is just an instance.
