1051 - Height Checker.Easy
A school is trying to take an annual photo of all the students. The students are asked to stand in a single file line in non-decreasing order by height. Let this ordering be represented by the integer array
expected
whereexpected[i]
is the expected height of theith
student in line.You are given an integer array
heights
representing the current order that the students are standing in. Eachheights[i]
is the height of theith
student in line ( 0-indexed ).Return the number of indices where
heights[i] != expected[i]
.Example 1:
Input: heights = [1,1,4,2,1,3]
Output: 3
Explanation:
heights: [1,1,4,2,1,3]
expected: [1,1,1,2,3,4]
Indices 2, 4, and 5 do not match.
Example 2:
Input: heights = [5,1,2,3,4]
Output: 5
Explanation:
heights: [5,1,2,3,4]
expected: [1,2,3,4,5]
All indices do not match.
Example 3:
Input: heights = [1,2,3,4,5]
Output: 0
Explanation:
heights: [1,2,3,4,5]
expected: [1,2,3,4,5]
All indices match.
Constraints:
1 <= heights.length <= 100
1 <= heights[i] <= 100
