I am bit confuse how the slice works in case a negative step is supplied
a = 'abcde'
a[::-1] gives me edcba
but [4:0:-1] gives me edcb
while searching net I came accross something which said the following:
If a negative stride is specified and the starting or stopping indices are
omitted, they default to ``end of axis'' and ``beginning of axis''
In my case 4 is end of axis and 0 is begining of the axis so a[::-1] should
be equivalent to [4:0:-1] but result which I get in both the cases does not
