 if t is [1]                then Test5C.sumSkip(t) returns 1 
 if t is [-1, 2]            then Test5C.sumSkip(t) returns -1 
 if t is [1, 2, 8]          then Test5C.sumSkip(t) returns 9 
 if t is [1, 0, -9, 4]      then Test5C.sumSkip(t) returns -8 
 if t is [1, 2, 12, -3, 15] then Test5C.sumSkip(t) returns 28
