zoho taxi question (3rd Round)

Taxi application Design a Call taxi booking application -There are n number of taxi’s. For simplicity, assume 4. But it should work for any number of taxi’s. -The are 6 points(A,B,C,D,E,F) -All the points are in a straight line, and each point is 15kms away from the adjacent points. -It takes 60 mins to travel from one point to another -Each taxi charges Rs.100 minimum for the first 5 kilometers and Rs.10 for the subsequent kilometers. -For simplicity, time can be entered as absolute time. Eg: 9hrs, 15hrs etc. -All taxi’s are initially stationed at A. -When a customer books a Taxi, a free taxi at that point is allocated -If no free taxi is available at that point, a free taxi at the nearest point is allocated. -If two taxi’s are free at the same point, one with lower earning is allocated -Note that the taxi only charges the customer from the pickup point to the drop point. Not the distance it travels from an adjacent point to pickup the customer. -If no taxi is free a...

Inser 0 after Consecutive (K times) Of 1 is Found

Example: Input: Number of bits: 12 Bits: 1 0 1 1 0 1 1 0 1 1 1 1 Consecutive K: 2 Output: 1 0 1 1 0 0 1 1 0 0 1 1 0 1 1 0 //JAVA CODE import java.util.Scanner; public class Main { public static void main(String[] args) { Scanner sc= new Scanner(System. in ); int n = sc.nextInt(); int k=sc.nextInt(); int []a = new int [n]; int temp= 0 ; //Inputs for ( int i= 0 ;i<n;i++) a[i]=sc.nextInt(); //print for ( int i= 0 ;i<n;i++){ System. out .print(a[i]+ " " ); if (a[i]== 1 ){ temp++; if (temp==k) { System. out .print( "0 " ); temp= 0 ; } } else temp= 0 ; } } }
