Answer / cmos

This can be done by recursion.
Since the number of recursive calls is not significant, it does not affect the performance much

printnumber(int i)
{
if(i == 0)
return;
printnumber(i/10);
putchar(’0′ + i%10);
}

Given an array of characters which form a sentence of words, give an efficient algorithm to reverse the order of the words (not characters) in it.
