# [775. Global and Local Inversions](https://leetcode.com/problems/global-and-local-inversions/)
## 题目
We have some permutation `A` of `[0, 1, ..., N - 1]`, where `N` is the length of `A`.
The number of (global) inversions is the number of `i < j` with `0 <= i < j < N` and `A[i] > A[j]`.
The number of local inversions is the number of `i` with `0 <= i < N` and `A[i] > A[i+1]`.
Return `true` if and only if the number of global inversions is equal to the number of local inversions.
**Example 1:**
```
Input: A = [1,0,2]
Output: true
Explanation: There is 1 global inversion, and 1 local inversion.
```
**Example 2:**
```
Input: A = [1,2,0]
Output: false
Explanation: There are 2 global inversions, and 1 local inversion.
```
**Note:**
- `A` will be a permutation of `[0, 1, ..., A.length - 1]`.
- `A` will have length in range `[1, 5000]`.
- The time limit for this problem has been reduced.
## 题目大意
数组 A  [0, 1, ..., N - 1] 的一种排列N 是数组 A 的长度。全局倒置指的是 i,j 满足 0 <= i < j < N 并且 A[i] > A[j] ,局部倒置指的是 i 满足 0 <= i < N 并且 A[i] > A[i+1] 。当数组 A 中全局倒置的数量等于局部倒置的数量时返回 true 。
## 解题思路
- 本题代码非常简单,重在思考的过程。`[0, 1, ..., N - 1]` 不出现全局倒置的理想情况应该是 `i` 排列在 `A[i-1]``A[i]``A[i+1]` 的位置上。例如 `1` 如果排列在 `A[3]` 的位置上,那么比 `1` 小的只有 `0` 一个元素,`A[0]``A[1]``A[2]` 中必定有 2 个元素比 `1` 大,那必须会出现全局倒置的情况。`[0, 1, ..., N - 1]` 这是最理想的情况,每个元素都在自己的位置上。每个元素如果往左右相互偏移 1 个元素,那么也能保证只存在局部倒置,如果左右偏移 2 个元素,那必定会出现全局倒置。所以结论是:**不出现全局倒置的理想情况应该是 `i` 排列在 `A[i-1]``A[i]``A[i+1]` 的位置上**。判断这个结论的代码很简单,只需要判断 `A[i] - i` 的取值是否是 -101也即 `abs(A[i] - i ) ≤ 1`
## 代码
```go
package leetcode
func isIdealPermutation(A []int) bool {
for i := range A {
if abs(A[i]-i) > 1 {
return false
}
}
return true
}
func abs(a int) int {
if a < 0 {
return -a

return a
