Let the following grammar describes the syntax of expression that has the form:

G = <list of digit separated by + or - signs>

  list -> list + digit 

  list ->list – digit                                       

  list ->digit                                                

  digit -> 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9  

Give leftmost and rightmost derivation for the CFG above to resolve the example  9 - 5 + 2  and draw parse trees for both of the derivations
