Answer / meera
creating copies takes extra memory. it is anlaogus to have a complete duplicate of the mapping. whereas shortcut refers to the refrence for the mapping. when creating shortcut memory is not used up . and any change made to the original reference (mapping) will be reflected in the shortcut.
