Given two strings 'STR' and 'PTR', identify all starting indices of 'PTR' anagram substrings in 'STR'. Two strings are anagrams if one can be rearranged to form the other.
Input:
...read more
Ans. 
Implement a function to find all starting indices of anagram substrings of a given string in another string.
• Create a frequency map of characters in the 'PTR' string.

• Use a sliding window approach to check for anagrams in 'STR'.

• Return the starting indices of anagram substrings found.

• Example: For input 'BACDGABCD' and 'ABCD', output should be [0, 5].
