Alice manages a company and has rented some floors of a building as office space. Alice has decided some of these floors should be special floors, used for relaxation only.
You are given two integers bottom
and top
, which denote that Alice has rented all the floors from bottom
to top
(inclusive). You are also given the integer array special
, where special[i]
denotes a special floor that Alice has designated for relaxation.
Return the maximum number of consecutive floors without a special floor.
Example 1:
Input: bottom = 2, top = 9, special = [4,6]
Output: 3
Explanation: The following are the ranges (inclusive) of consecutive floors without a special floor:
(2, 3) with a total amount of 2 floors.
(5, 5) with a total amount of 1 floor.
(7, 9) with a total amount of 3 floors.
Therefore, we return the maximum number which is 3 floors.
Example 2:
Input: bottom = 6, top = 8, special = [7,6,8]
Output: 0
Explanation: Every floor rented is a special floor, so we return 0.
Constraints:
1 <= special.length <= 105
1 <= bottom <= special[i] <= top <= 109
special
are unique.class Solution {
fun maxConsecutive(bottom: Int, top: Int, special: IntArray): Int {
special.sort()
var start = bottom
var ans = 0
for (j in special) {
if (j - start > ans) {
ans = j - start
start = j + 1
} else {
start = j + 1
}
}
if (ans < top - special[special.size - 1]) {
ans = top - special[special.size - 1]
}
return ans
}
