Corona Virus Codevita 9 Solution

Problem Description

A city is spoken to as two-dimensional rectangular grid. The external mass of the given grid indicates the limits of the city. Residents are scattered in the city at various areas. They are either delineated by {a, c}. Covid has just tainted the city. 

 

The Corona Virus enters the city from organize (0, 0) and navigates along a corner to corner way until it experiences a human. On the off chance that it experiences a human, assigned as a , its direction pivots against clockwise (option to left) by 90 degrees. Likewise, on the off chance that it experiences a human, assigned as c , its direction turns clockwise (left to right) by 90 degrees. Subsequent to tainting the individual, the infection keeps on moving along its slanting way. 

 

During its crossing in the event that it hits the limit of the city just because, it turns 90 degrees to reemerge the city. Notwithstanding on the off chance that it hits any of the limit divider, the subsequent time, the infection gets crushed. 

 

You need to compute the direction taken by the infection, print the city map where contaminated residents can be found lastly report the quantity of sheltered and tainted residents. 

 

Information 

 

An information framework of 9 lines and 20 segments including {*, a, c, . } characters where 

 

* indicates a component on the limits of the city 

 

an indicates resident subsequent to experiencing whom the infection direction changes by 90 degrees (hostile to clockwise bearing) 

 

c means resident in the wake of experiencing whom the infection direction changes by 90 degrees (clockwise bearing) 

 

. (spot) means void area inside the city 

 

Yield 

 

Arbitrary number of lines each meaning the directions of the direction of the infection. 

 

From next line a yield grid of 9 lines and 20 segments containing {*, a, c, ., – } characters where 

 

* signifies a component on the limits of the city 

 

a signifies resident in the wake of experiencing whom the infection direction changes by 90 degrees (against clockwise heading) 

 

c signifies resident subsequent to experiencing whom the infection direction changes by 90 degrees (clockwise heading) 

 

. (speck) means void area inside the city 

 

– signifies the area of the contaminated resident 

 

What’s more, the following two lines print the quantity of sheltered and contaminated residents in the city 

 

Allude Examples segment for better understanding. 

 

Limitations 

 

0 <= x <= 20 

 

0 <= y <= 8 

 

The infection can’t hit the three corners (20, 8) (20, 0) (0, 8)

Clarification 

 

The infection direction begins from (0,0) and crosses (1,1) (2,2). At (2,2) we have a resident of type a making the infection direction be turned by 90 degrees against clockwise. It moves until the following resident in its way is experienced at (1, 3) of type c making the infection direction be pivoted by 90 degree clockwise. It proceeds on its way till it arrives at the following human in its way at (4,6) of type c Virus direction is again pivoted by 90 degrees clockwise until it hits the limit at (10,0). Since this is the first occasion when that the infection hits the limit, it pivots by 90 degrees anticlockwise to return the city. The direction at that point proceeds towards (11,1) (12,2) (13,3) lastly a resident at (14,4) of type a pivoting the direction to 90 degree anticlockwise. From that point it proceeds with its direction and hits the limit at (10,8). 

 

Since this is the second time the infection hits the limit, the infection is devastated. 

 

In this way, along its direction beginning from (0,0) it has tainted 4 residents at area (2,2) (1,3) (4,6) (14,4). The other 4 residents who didn’t come in the infection direction are considered to be sheltered.

Clarification 

 

The infection direction begins from (0,0) and crosses (1,1) (2,2) (5,5). At (5,5) we have a resident of type c making the infection direction be pivoted by 90 degrees clockwise. It moves until the following resident in its way is experienced at (8,2) of type a making the infection direction be pivoted by 90 degree hostile to clockwise. It proceeds on its way till it arrives at the following human in its way at (10,4) of type a Virus direction is again pivoted by 90 degrees clockwise until it hits the limit at (6,8). Since this is the first occasion when that the infection hits the limit, it pivots by 90 degrees anticlockwise to reemerge the city. The direction at that point proceeds towards (9,5) (8,6) (7,7) (6,8) and leaseholders the city by turning the direction by 90 degrees against clockwise to follow the direction (5,7) (4,6) (3,5) (2,4) (1,3) (0,2). 

 

At (0,2) it again hits the limit and since this is the second time the infection hits the limit, the infection is obliterated. So along its direction beginning from (0,0) it has contaminated 3 residents at area (5,5) (10,4) (8,2). The other 2 residents who didn’t come in the infection direction are considered to be sheltered.
