Given an integer array `nums` and two integers `k` and `t`, return `true` if there are **two distinct indices** `i` and `j` in the array such that `abs(nums[i] - nums[j]) <= t` and `abs(i - j) <= k`.
**Example 1:**
**Input:** nums = [1,2,3,1], k = 3, t = 0
**Output:** true
**Example 2:**
**Input:** nums = [1,0,1,1], k = 1, t = 2
**Output:** true
**Example 3:**
**Input:** nums = [1,5,9,1,5,9], k = 2, t = 3
**Output:** false
**Constraints:**
* 1 <= nums.length <= 2 * 104
* -231 <= nums[i] <= 231 - 1
* 0 <= k <= 104
* 0 <= t <= 231 - 1
