0/120
Asked in companies
There is a country with 'N' cities and 'M' bidirectional roads of 3 types.
Type 1: Two Wheeler Road, It means only vehicles having two wheels can use this road.
Type 2: Four Wheeler Road, It means only vehicles having four wheels can use this road.
Type 3: Both two and four Wheeler Road, It means this road can be used by both type of vehicles.
The problem is to find the maximum number of roads that can be removed such that a path exists for every pair of cities for each two-wheeler and four-wheeler vehicle.
Note:
1. Roads may form a cycle.
2. The cities do not have multiple same roads i.e all the roads are unique.
3. If every city cannot be reached, then return -1.
Problem approach
#include
int main()
{ int v,w;
//V is total of four wheeler and two wheeler
printf(“enter value of v:”);
scanf(“%d”, &v); //W is total of wheels of four wheeler and two wheeler printf(“enter value of w”);
scanf(“%d”, &w); if(v>w || w%2!=0 || 2>=w)
{
printf(“you enter invalid input”);
}
else
{
printf(“you enter valid input”); int t, f;
int a=w/2;
f=a-v;
t=v-f;
printf(“total number of four wheeler is: %d”,f); printf(“total number of two wheeler is : %d\n”,t); }
