最小化战斗力差距可以使用以下方法来实现:
1. 使用排序:将战斗力数组进行排序,然后计算相邻元素之间的差值,找到最小的差值即可。
```python
def minimize_power_difference(nums):
nums.sort()
min_diff = float('inf')
for i in range(len(nums) - 1):
diff = nums[i+1] - nums[i]
min_diff = min(min_diff, diff)
return min_diff
```
2. 使用动态规划:创建一个二维数组dp,其中dp[i][j]表示前i个战斗力中选择j个人的最小差值。通过状态转移方程dp[i][j] = min(dp[i-1][j], dp[i-1][j-1] + nums[i-1])来更新dp数组,最后返回dp[len(nums)][len(nums)//2]即可。
```python
def minimize_power_difference(nums):
nums.sort()
n = len(nums)
dp = [[float('inf')] * (n//2 + 1) for _ in range(n+1)]
dp[0][0] = 0
for i in range(1, n+1):
for j in range(1, min(i//2+1, n//2+1)):
dp[i][j] = min(dp[i-1][j], dp[i-1][j-1] + nums[i-1])
return dp[n][n//2]
```
