+# Boats to save people
+
+A big ship with numerous passengers is sinking, and there is a need to evacuate these people with the minimum number of 
+life-saving boats. Each boat can carry, at most, two persons however, the weight of the people cannot exceed the 
+carrying weight limit of the boat.
+
+We are given an array, people, where people[i] is the weight of the `ith` person, and an infinite number of boats, where
+each boat can carry a maximum weight, limit. Each boat carries, at most, two people at the same time. This is provided 
+that the sum of the weight of these people is under or equal to the weight limit.
+
+You need to return the minimum number of boats to carry all persons in the array.
+
+## Constraints
+
+- 1 <= `people.length` <= 5 * 10^3
+- 1 <= `people[i]` <= `limit` <= 3 * 10^3
+
+## Examples
+
+![Example 1](./images/examples/boats_to_save_people_example_1.png)
+![Example 2](./images/examples/boats_to_save_people_example_2.png)
+![Example 3](./images/examples/boats_to_save_people_example_3.png)
+![Example 4](./images/examples/boats_to_save_people_example_4.png)
+![Example 5](./images/examples/boats_to_save_people_example_5.png)
+
+## Solution
+
+1. [Naive Approach](#naive-approach)
+2. [Optimized Approach Using Greedy Pattern](#greedy-pattern)
+
+### Naive Approach
+
+The naive approach is to use a nested loop. For each person, we can check all the remaining people to see if they can 
+form a pair that fits into a boat. If we find a pair, we’ll remove them from the array, increment the number of boats 
+used, and move to the next person. If we can’t find a pair for a person, we put them in a boat alone and increment the 
+number of boats used. We repeat this process until all people are rescued.
+
+The time complexity of this approach is O(n^2), since we’ll use the nested loop to make pairs.
+
+### Greedy Pattern
+
+To solve the problem, we can use the greedy pattern and pair people with the lightest and heaviest people available, as 
+long as their combined weight does not exceed the weight limit. If the combined weight exceeds the limit, we can only 
+send one person on that boat. This approach ensures that we use the minimum number of boats to rescue the people.
+
+The steps to implement the approach above are given below:
+
+1. Sort the people array in ascending order so that the lightest person is at the start of the array, and the heaviest 
+   person is at the end.
+
+2. Initialize two pointers, left and right. The left pointer points to the lightest person at the start of the array, 
+   and the right pointer points to the heaviest person at the end of the array. Next, a variable, boats, is initialized 
+   to 0, representing the number of boats used.
+
+3. Iterate over the people array until the left pointer is greater than the right pointer. This means that all people 
+   have been rescued. Perform the following steps in each iteration of the loop 
+   - Check if both the lightest and heaviest persons can fit in one boat, i.e., people[left] + people[right] is less 
+     than or equal to limit. If they can fit, the left pointer is incremented and the right pointer is decremented.
+   - If they cannot fit in one boat, the heaviest person is rescued alone, and the right pointer is decremented. 
+   - The boats variable is incremented by 1, representing the number of boats used.
+
+4. Return the minimum number of boats required to rescue all the people.

+
+#### Solution Summary
+
+- Sort the people array. 
+- Initialize two pointers—left at the start and right at the end of the array. 
+- Iterate over the people array while the left pointer is less than or equal to the right pointer.
+  - Check if both the lightest and heaviest persons can fit in one boat. If so, increment the left pointer and decrement 
+    the right pointer.
+  - Otherwise, rescue the heaviest person alone and decrement the right pointer. 
+  - Increment the boats after each rescue operation.
+
+#### Time Complexity
+
+The time complexity for the solution is O(n log n), since sorting the people array takes O(n log n) time.
+
+#### Space Complexity
+
+The sorting algorithm takes O(n) space to sort the people array. Therefore, the space complexity of the solution above 
+is O(n).
