 **2.1.4** Write a function ''​realtrycatch''​ where t and c take no parameters and produce a result upon evaluation. If an error occurs (try function returns 0), the catch function will be called instead. **2.1.4** Write a function ''​realtrycatch''​ where t and c take no parameters and produce a result upon evaluation.

 **2.2.1** Define the function ''​foldWith''​ which uses an operation ''​op''​ to reduce a range of integers to a value. For instance, given that ''​op''​ is addition (+), the result of folding the range 1 to 3 will be 1+2+3=6. ''​foldWith''​ should be curried (it will take the operation and return another function which expects the bounds). **2.2.1** Define the function ''​foldWith''​ which uses an operation ''​op''​ to reduce a range of integers to a value.
