I have an single dimensional array of Strings.

Eg:

Arr[0] = "124124"
Arr[1] = "42314"
Arr[2] = "as35"
etc.

I will have to return true if the string contained in the array is an interger. That means

Arr[0] returns True
Arr[1] returns True
Arr[2] returns False.

Any suggestions are welcome. Please guide me.
