write a program to reverse the words in a give string.
also state the time complexity of the algo.
if the string is i am a programmer
the output should be programmer a am i

reverse(string,n) // do it in place
p = str;
for(i=0;ilength(str);i++)
{

reverse(p,len);
p = p+len+1;
len = 0;

len++;

@ MeHdi : Please read the problem properly yaar. You are just reversing the
string by characters, not by words.

It has already been discussed on the list a few days ago
if the string is i am a programmer
the output should
method 1:
algo:
step 1 :reverse entire string .. (letter by letter)
step 2: take two pointers ... keep first pointer at the starting of the word
... keep incrementing the second pointer , till space hits.. then , swap
first pointer and second pointere data , by incrementing first pointer , and
@gopi: Each word is being accessed thrice.
1. reverse string
2. set pointers to beginning n end of string
3. reverse the word.
If this is the came is the complexity O(n)??
It's a very good algo nevertheless :)

First reverse the senetence word by word and then reverse the whole
stringthat will be easier
