Rearrange characters in a string such that no two adjacent are same: To view question , click here http://www.interviewrack.com/2017/03/rearrange-characters-in-string-such.html Prerequisite :  priority_queue . The idea is to put highest frequency character first (a greedy approach). We use a priority queue (Or Binary Max Heap) and put all characters and ordered by their frequencies (highest frequency character at root). We one by one take highest frequency character from the heap and add it to result. After we add, we decrease frequency of the character and we temporarily move this character out of priority queue so that it is not picked next time. We have to follow the step to solve this problem, they are: 1. Build a Priority_queue or max_heap,  pq  that stores characters and their frequencies. …… Priority_queue or max_heap is built on the bases of frequency of character. 2. Create a temporary Key that will used as the previous visited element ( prev...
