WebSep 12, 2024 · Consider the binary representation of num with n bits. Start from the leftmost bit which represents 1, the second bit represents 2, and so on until nth bit which represents n. Print the number corresponding to the bit if it is set. Perform the above steps for all values of num until it is equal to 0. Considering input n = 4, start from . WebMay 31, 2013 · 2. Basically the algorithm returns all subsets of groupSize (which should really be renamed to group ), that have k elements. The method works recursively. To do so it needs two things : establish primitive cases that end the recursion, and a way of formulating the problem in terms of itself, yet closer to the primitive form.
