IntuitExpedia GroupBNY Mellon

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

I first applied a loop through input 1. If the value at input 1 isn't present at input 2 then the count is increased. Do the same for input2. Print count

You're given a string 'S' consisting of "{", "}", "(", ")", "[" and "]" .


Return true if the given string 'S' is balanced, else return false.


For example:
'S' = "{}()".

There is always an opening brace before a closing brace i.e. '{' before '}', '(' before ').
So the 'S' is Balanced.
Problem approach

Add the brackets in a stack. Pop the stack and verify that the brackets are balanced
