A scheduler manages multiple processes with priorities represented by the letters a, b, and c. Its goal is to optimize the schedule to achieve a specific sequence.
The operations available to the scheduler are as follows:
Determine the minimum number of scheduling operations required to ensure that the scheduling queue follows the repeating pattern "abc".
Complete the function findMinOperations in the editor below.
findMinOperations takes the following parameters:
- string s: the scheduling queue
Returns
int: the minimum number of operations required to make the queue a concatenation of 'abc' several times
Constraints
- 1 ≤ |s| ≤ 10^5
- s consists only of characters 'a', 'b', and 'c'.
s = "abb" return = 3
Transform the queue to abcabc by inserting two letters c and one letter a. The string "abcabc" is the concatenation of "abc" two times.
The minimum number of scheduling operations required is 3.
s = "aa" return = 4
Insert 'b' and 'c' after the first and second 'a' to transform the string to abcabc.
s = "ac" return = 1
Insert 'b' between 'a' and 'c' to transform the string to abc.
