For example, 1248 and 1428 are anagrams of 1284, eat and ate are anagrams of tea, and AABC is an anagram of ABCA. Write the following programs for detecting anagrams 1.1 A program to implement a brute force algorithm. (10%) 1.2 A more efficient program based on the presorting technique. (20%) When a program is executed, t reads in the 30000 strings in file data 4.txt, prompts for a string, finds al the anagrams of the string (not including the string), displays the anagrams, and reports the total umber of anagrams found. A proram is required to report the running time for each search (for 1.1 search time, and for 1.2 sorting and search time separately
