Array1 has 3, 5,7 and array2 has 1,4,9 how to merger these two arrays as single array with elements are in sorting order.

Can i first sort the arrays individually an then merging or first merging the 2 arrays and then do sorting ?

you can do it either way.


There are only two hard things in computer science: cache invalidation, naming things, and off-by-one errors
