### Instructions: You are an expert Python programmer. You will be given a question (problem specification) and the first lines of Python solution to this problem, and will write in Python the remaining lines of the program to produce a correct Python program that matches the specification and passes all tests. You will NOT return anything except for the second part of the program that you wrote.
### Question:
You are given a 0-indexed integer array coins, representing the values of the coins available, and an integer target.
An integer x is obtainable if there exists a subsequence of coins that sums to x.
Return the minimum number of coins of any value that need to be added to the array so that every integer in the range [1, target] is obtainable.
A subsequence of an array is a new non-empty array that is formed from the original array by deleting some (possibly none) of the elements without disturbing the relative positions of the remaining elements.

Example 1:

Input: coins = [1,4,10], target = 19
Output: 2
Explanation: We need to add coins 2 and 8. The resulting array will be [1,2,4,8,10].
It can be shown that all integers from 1 to 19 are obtainable from the resulting array, and that 2 is the minimum number of coins that need to be added to the array.

Example 2:

Input: coins = [1,4,10,5,7,19], target = 19
Output: 1
Explanation: We only need to add the coin 2. The resulting array will be [1,2,4,5,7,10,19].
It can be shown that all integers from 1 to 19 are obtainable from the resulting array, and that 1 is the minimum number of coins that need to be added to the array.

Example 3:

Input: coins = [1,1,1], target = 20
Output: 3
Explanation: We need to add coins 4, 8, and 16. The resulting array will be [1,1,1,4,8,16].
It can be shown that all integers from 1 to 20 are obtainable from the resulting array, and that 3 is the minimum number of coins that need to be added to the array.


Constraints:

1 <= target <= 10^5
1 <= coins.length <= 10^5
1 <= coins[i] <= target

### Format: You will use the following starter code to write the solution to the problem and enclose your code within delimiters.
```python
class Solution(object):
def minimumAddedCoins(self, coins, target):
"""
:type coins: List[int]
:type target: int
:rtype: int
"""
coins.sort()
result = reachable = 0
for x in coins:
# if x > target:
# break
while not reachable >= x-1:
result += 1
reachable += reachable+1
reachable += x
while not reachable >= target:
```

### Answer: (enclose your partial completion in backticks. Only write the missing portion of the code, not the entire code. Be very careful to match the appropriate indentation. Directly appending your code after the partial code should produce a correct completion solution.)

### Explanation:

The given starter code sorts the `coins` array and initializes `result` and `reachable` to 0. The `result` variable keeps track of the minimum number of coins to be added, while the `reachable` variable represents the maximum obtainable integer using the current set of coins (including the added ones).

The code then iterates over each coin `x` in the sorted `coins` array. Within this loop, there is a commented-out section that suggests breaking the loop if `x` exceeds the `target`. However, this breaking condition is not necessary because we want to process all coins in the array, even if they are larger than the target. The reason is that larger coins might help us reach smaller unobtainable numbers in between.

The key part of the loop is the `while` condition that checks if `reachable` is less than `x-1`. If it is, it means there are gaps in the obtainable numbers before we can use coin `x`. To fill these gaps, we add new coins (increment `result`) and update `reachable` accordingly. The value added to `reachable` is `reachable+1`, which represents the next obtainable number. This process continues until `reachable` is at least `x-1`, ensuring that we can use coin `x` without leaving any gaps.

After processing all the coins, we have a final `while` loop that checks if `reachable` is still less than the `target`. If it is, we need to add more coins to reach the target. Similar to the previous `while` loop, we increment `result` and update `reachable` until `reachable` is at least `target`.

Finally, we return the `result`, which represents the minimum number of coins added to make every integer in the range `[1, target]` obtainable.		 class Solution(object): def minimumAddedCoins(self, coins, target): """ :type coins: List[int] :type target: int :rtype: int """ coins.sort() result = reachable = 0 for x in coins: # if x > target: # break while not reachable >= x-1: result += 1 reachable += reachable+1 reachable += x while not reachable >= target: result += 1 reachable += reachable+1 return result
