also state the time complexity of the algo.
if the string is "i am a programmer"
the output should be "programmer a am i"

The internal representation of array is this:
suppose that the address starts from decimal number 10 and integer occupies
2 bytes
10- 0002 ( num 2 in hex)
12- 0003 ( num 3 in hex)
14- 0004 ( num 4 in hex)
Now p points to address 10 and is type char. (Even after type casts) p+1
will increment add

Correct me if i'm wrong. I think it's cos at a time it'll fetch the amount
of bytes = to it's register's size.
If a 32-bit machine is being used, answer will contain 4 bytes
ff81
16-bit machine - ff81

got it!
@sagar there shudn be 2's anywhere in the expression.
The different combinations formed on the left hand side by choosing 6 out of
12 will ensure different combinations of other 6 people on the right. So
2*12C6 is not required.
Example:
P1,P3,P5,P7,P9, P11
on left will leave
P2, P4, P6, P8,
left- 12C6*6C2
right- 12C6*6C3
Why is 6C2*6C3 combined in a single expression??

@Dave: I guess 17/18 is correct. Since we have to *calculate the probability
of getting a head in the 6th flip given that first 5 flips are a head*. Can
you please explain how you got the values of consequent flips when you said
this?
*"In fact, the probability is 3/5 for the first flip. After a h
delete function will set parent->left_leaf=null and parent->right_leaf=null
as a part of it's function. So after deletion of leaf nodes, the call
returns to the parent nodes which are the current leaf nodes. Hence the
option must be *deletion of the tree from bottom to top*.

Traverse the tree inorder. Store the values in an array. Find the element in
the middle of the array.
