Asked in companies
You have been given an array/list of strings 'inputStr'. You are supposed to return the strings as groups of anagrams such that strings belonging to a particular group are anagrams of one another.
An anagram is a word or phrase formed by rearranging the letters of a different word or phrase. We can generalize this in string processing by saying that an anagram of a string is another string with the same quantity of each character in it, in any order.
Note:
The order in which the groups and members of the groups are printed does not matter.
For example:
inputStr = {"eat","tea","tan","ate","nat","bat"}
Here {“tea”, “ate”,” eat”} and {“nat”, “tan”} are grouped as anagrams. Since there is no such string in “inputStr” which can be an anagram of “bat”, thus, “bat” will be the only member in its group.
Problem approach
1. Sort the given string.
2. Open the words.txt file using file handling ifstream to read the file in C++ as: ifstream words(“file.txt”);
3. For each word in the file words.txt sort the word and compare it with the given sorted string.
4. If both the string matches in the above step then print the current word in the file words.txt.
5. Close the file after all the words has been checked.
