Problem Brief

Chairs Requirement

FULLTIMEOA

See IBM online assessment and hiring insights

In this challenge, determine the minimum number of chairs to be purchased to accommodate all workers in a new business workroom. There is no chair at the beginning.

There will be a string array of simulations. Each simulation is described by a combination of four characters: C, R, U, and L

C - A new employee arrives in the workroom. If there is a chair available, the employee takes it. Otherwise, a new one is purchased.
R - An employee goes to a meeting room, freeing up a chair.
U - An employee arrives from a meeting room. If there is a chair available, the employee takes it. Otherwise, a new one is purchased.
L - An employee leaves the workroom, freeing up a chair.

Function Description

Complete the minChair function.

minChair has the following parameter(s):

string simulation[n]: an array of strings representing discrete simulations to process.

Return

int[n]: an array of integers denoting the minimal number of chairs required for each simulation.

1Example 1

Input

simulation = ["CRUL"]

Output

[1]

Explanation

In this case, there is only one simulation, CRUL, represented in the table above.

At first, there are 0 chairs.

"C": A new employee arrives in the workroom and one chair was purchased.

"R": An employee goes to the meeting room, freeing up a chair.

"U": An employee arrives from the meeting room, took the chair available.

"L": An employee leaves the workroom, freeing up a chair.

The minimum number of chairs to be purchased in one chair in this case. Result = [1].

Constraints

Limits and guarantees your solution can rely on.

1 ≤ n ≤ 100
1 ≤ length of each simulation[i] ≤ 10000
