题号 781. 森林中的兔子
森林中,每个兔子都有颜色。其中一些兔子(可能是全部)告诉你还有多少其他的兔子和自己有相同的颜色。我们将这些回答放在 answers 数组里。
返回森林中兔子的最少数量。
示例:
输入: answers = [1, 1, 2]
输出: 5
解释:
两只回答了 "1" 的兔子可能有相同的颜色,设为红色。
之后回答了 "2" 的兔子不会是红色,否则他们的回答会相互矛盾。
设回答了 "2" 的兔子为蓝色。
此外,森林中还应有另外 2 只蓝色兔子的回答没有包含在数组中。
因此森林中兔子的最少数量是 5: 3 只回答的和 2 只没有回答的。
输入: answers = [10, 10, 10]
输出: 11
输入: answers = []
输出: 0
说明:
answers 的长度最大为1000。
answers[i] 是在 [0, 999] 范围内的整数。
