Minimum removals required such that a string can be rearranged to form a palindrome | Function to find the number of deletions required such that characters of the string can be rearranged to form a palindrome.
Stores frequency of characters.
Store the frequency of each character in frequency array.
Count number of characters with odd frequency.
If count is 1 or 0 , return 0.
Otherwise , return count - 1.
