2057 - Smallest Index With Equal Value.

Easy

Given a 0-indexed integer array nums, return the smallest index i of nums such that i mod 10 == nums[i], or -1 if such index does not exist.

x mod y denotes the remainder when x is divided by y.

Example 1:

Input: nums = [0,1,2]

Output: 0

Explanation:

i=0: 0 mod 10 = 0 == nums[0].

i=1: 1 mod 10 = 1 == nums[1].

i=2: 2 mod 10 = 2 == nums[2].

All indices have i mod 10 == nums[i], so we return the smallest index 0.

Example 2:

Input: nums = [4,3,2,1]

Output: 2

Explanation:

i=0: 0 mod 10 = 0 != nums[0].

i=1: 1 mod 10 = 1 != nums[1].

i=2: 2 mod 10 = 2 == nums[2].

i=3: 3 mod 10 = 3 != nums[3].

2 is the only index which has i mod 10 == nums[i].

Example 3:

Input: nums = [1,2,3,4,5,6,7,8,9,0]

Output: -1

Explanation: No index satisfies i mod 10 == nums[i].

Constraints:

  • 1 <= nums.length <= 100
  • 0 <= nums[i] <= 9
