Question 2 : Loki’s Mind Stone

Problem Statement :

Loki, the God of mischief can brainwash any living person by touching him/her with his Mind stone, and has decided to break the avengers (a warrior group) to face into each other, so that they can turn against each other and make Loki’s evil plans easier. Now all the avengers have some amount of strength that is denoted in integers. Loki wants to brainwash the least amount of people possible, because he is lazy. But he wants his team of avengers to win the battle. What is the number of avengers Loki will get brainwashed.

Question 5 : Minimizing a string

Problem Statement :

Given a string, obtain the alphabetically smallest string possible by swapping either
adjacent ‘a’ and ‘b’ characters or adjacent ‘b’ and ‘c’ characters, any number of times.

Note: A string x is alphabetically smaller
than a string y if, for the first index i where x
and y differs, x[i] <y[i].

Example :
s=”abaacbac”

The alphabetically smallest possible string is
obtained by applying the following
operations:

‘c’at index 5 is swapped with ‘b’at index 6. So “abaacbac” becomes “abaabcac”
Then,’b’at index 2 is swapped with ‘a’at index 3. So “abaabcac” becomes “aababcac”.
Finally, ‘b’at index 3 is swapped with ‘a’at index 4 to obtain the final.
answer: “aaabbcac”.

Function Description :
Complete the function smallestString in the
editor below.

smallestString has the following
parameter(s):

string s: the given string
Returns:
string: the lexicographically smallest string obtained after swapping

Constraints :

1 <_ length of s<_ 10^5 s only contains the characters ‘a’, ‘b’, and ‘c’.
