Given a string, sort it in decreasing order based on the frequency of characters.Example 1:Input: "tree" Output: "eert" Explanation: 'e' appears twice while 'r' and 't' both appear once. So 'e' must appear before both 'r' and 't'. Therefore "eetr" is also a valid answer. ...
(a) If all the elements in an array are sorted in decreasing order and we want them in increasing order, which sorting algorithm will be asymptotically the fastest; insertion sort, quick short, merge Briefly explain the purpose of the loop, or iteration, structure. Then provide an original ...
In the above program, we can see we have already declared a set of strings in an array and then we are comparing adjacent strings and swapping them using temp variable. Then we are arranging the given array in an alphabetical order which is done using bubble sort. The output can be seen...
