WebThe test cases are generated such that the number of unique combinations that sum up to target is less than 150 combinations for the given input. Example 1: Input: candidates = [2,3,6,7], target = 7 Output: [ [2,2,3], [7]] Explanation: 2 and 3 are candidates, and 2 + 2 + 3 = 7. Note that 2 can be used multiple times. 7 is a candidate, and 7 = 7. WebNov 23, 2024 · Given an array of size n, generate and print all possible combinations of r elements in array. Examples: Input : arr [] = [1, 2, 3, 4], r = 2 Output : [ [1, 2], [1, 3], [1, 4], [2, 3], [2, 4], [3, 4]] Recommended: Please try your approach on {IDE} first, before moving on to …

WebMay 23, 2024 · The goal was to find all possible combinations of choosing k elements from a n-sized array (basically the Binomial coefficient) and return them. Unlike this code - here I don't want all possible combinations, just those that are k in size. Permutations inside a k-size element are not counted (i.e. (1,2,3) == (2,1,3) == etc.).
