hi there, one of my friends asked me the solution to this problem. since i could not figure out the solution i decided to ask u guys. given a set of numbers, we are to print all possible combinations of numbers that can be formed using those numbers. for example, say we're given 1,2,3. the possible combinations are 123 132 213 231 321 312 this is a simple example. but the problem is to solve it for any number of integers. btw nested for loop doesn't work. please send across the code or the logic of the problem a.s.a.p. thanx. khuda hafiz firaz.
