Missing Number
Detailed guide and Python implementation for the 'Missing Number' problem.
Problem Statement
Given an array nums containing n distinct numbers in the range [0, n], return the only number in the range that is missing from the array.
Write a function missingNumber(nums: List[int]) -> int.
- •n == len(nums)
- •1 <= n <= 10^4
- •0 <= nums[i] <= n
- •All the numbers of nums are unique
Examples
nums = [3,0,1]
2
n = 3, range [0,3]. 2 is missing.
nums = [0,1]
2
n = 2, range [0,2]. 2 is missing.
nums = [9,6,4,2,3,5,7,0,1]
8
n = 9, range [0,9]. 8 is missing.
