Solution
The problem is asking to find the minimum number of deletions required to make two strings anagrams of each other. An anagram is a word or phrase formed by rearranging the letters of a different word or phrase, typically using all the original letters exactly once.
Here are the steps to solve this problem:
-
Initialize an array of size 26 (for each letter in the alphabet) to zero. This will be used to count the frequency of each letter in the strings.
-
Iterate over the first string. For each character, increment the corresponding index in the frequency array. For example, if the character is 'a', increment the value at index 0. If the character is 'b', increment the value at index 1, and so on.
-
Iterate over the second string. This time, decrement the corresponding index in the frequency array for each character.
-
After these steps, the frequency array will contain the difference in frequency of each character between the two strings. If the strings are anagrams, all values in the array will be zero.
-
To find the minimum number of deletions, sum up the absolute values of all the elements in the frequency array. This is because each non-zero value represents a character that needs to be deleted from one of the strings to make them anagrams.
-
Print the sum as the result.
This algorithm works because it counts the frequency of each character in the strings and then finds the difference. The sum of the absolute differences is the minimum number of deletions required to make the strings anagrams.
