A Dictionary class is a data structure that represents a collection of keys and values pair of data. The key is identical in a key-value pair and it can have at most one value in the dictionary, but a value can be associated with many different keys.
This class is defined in the System.Collections.Generic namespace, so you should import or using System.Collections.Generic namespace.
Dictionary<TKey,TValue>
TKey - The type of the keys in the dictionary.
TValue - The type of the values in the dictionary.
Input Occupancy String format:
Room_Adult_Children_Age : 1_2_1_10 [room always in string 1]
1_2_1_10 ; 1_2_1_8 or 1_2_1_10
; 1_2_1_8 ; 1_2_1_5
Output: 2_1_2_10_11
Input: 1_1_0_-1; 1_1_0_-1
Output: 2_1_0_-1
Input: 1_2_2_6_8 ; 1_2_2_4_6 ; 1_2_2_6_9
If you want to search for 2 single
room with 2 adult and 0 child you pass the occupancy like that:
Input: 1_2_0_-1 ; 1_2_0_-1
If 2 or 3
room then Input Occupancy string format:
Scenario 1: Search for 1
Adult
If you want to search for 1
single room with 1 adult and 0 child you pass the occupancy like that: Input: 1_1_0_-1
Where -1 stands for an age of
an adult which is not required so we pass it -1.
Scenario 2: Search for 1
Adult and 2 Children
If you want to search for 1
single room with 1 adult and 2 child you pass the occupancy like that:
Input: 1_1_1_10;1_1_1_11
where
10 stand for the first age of the first child and 11 stands for the second age
of the child.
Scenario 3: Search for 2
rooms one for 1 Adult and 0 Children and the Second for 2 Adults
If you want to search for 2
rooms with 1 adult and 0 children and another room for 2 adults and 0 children
you pass them like that:
Input: 1_1_0_-1;1_2_0_-1
Output: 1_1_0_-1;1_2_0_-1
Scenario 4: Search for 2
rooms for the same 1 Adult and 0 Children.
It will be like that
Scenario 5: Search for 3
rooms for the same 2 Adult and 2 Children.
It will be
like that
Output: 3_2_2_6_8_4_6_6_9
Scenario 6: Search for 2
Adult 0 Children
Output: 2_2_0_-1
