Journey
Before cracking any interview you need to prepare your basics. So, I started doing all the vital topics and subjects like DBMS, DSA, Networking, and Operating Systems. After preparing the top 100 or 150 questions on each topic I prepared all my projects and resume which was the most important step.

Asked in companies
You have been given two strings 'STR1' and 'STR2'. You have to check whether the two strings are anagram to each other or not.
Note:
Two strings are said to be anagram if they contain the same characters, irrespective of the order of the characters.
Example :
If 'STR1' = “listen” and 'STR2' = “silent” then the output will be 1.
Both the strings contain the same set of characters.
Problem approach
The first and the foremost condition for two strings to be the permutations of each other is that the frequency of each element in both of them should be the same.
It can be proven by a very simple argument that we are only rearranging the letters, and not adding or deleting any character.
So we allocate an array of size 256 (that is the number of distinct ASCIIacharactersterst to store the frequency.
For the first string, we increase the frequency of each of the characters and for the second one, we decrease one for every character encountered.
In the end, we check that each of the elements of this frequency array is 0 (total additions by the first string are exactly nullified by the second string).
If it is not zero we return false else we return true.
