InterviewBit SOLUTIONS Solution of all problems on www.interviewbit.com TOPIC : Arrays Math Binary Search Strings Bit Manipulation Two Pointers Linked Lists Stacks and Queues Backtracking Hashing Heaps and Maps Trees Dynamic Programming Greedy Graphs Code Ninja PROBLEM NAME : SEARCH Hello, The subarray must be contiguous so either you add the element of index i, or you start a new sum. * Also, the subsets should be sorted in ascending ( lexicographic ) order. To handle duplicate elements, we construct a string out of given subset such that subsets having similar elements will result in same string. There’s a third option: Stick with the solution at index i-1 and do not add element of index i to it. Note: * Elements in a subset must be in non-descending order. The same number may be chosen from candidates an unlimited number of times.Two combinations are unique if the frequency of at least one of the chosen numbers is different. ", Collection of Abhishek Agrawal's gists solutions for problems on.
