Asked in companies
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
1)Declare a character stack S.
2)Now traverse the expression string exp.
3)If the current character is a starting bracket (‘(‘ or ‘{‘ or ‘[‘) then push it to stack.
4)If the current character is a closing bracket (‘)’ or ‘}’ or ‘]’) then pop from stack and if the popped character is the matching starting bracket then fine else brackets are not balanced.
5)After complete traversal, if there is some starting bracket left in stack then “not balanced”

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
1)Sort both strings
2)Compare the sorted strings
