You are given a 0-indexed integer array
nums[i] is a digit between
The triangular sum of
nums is the value of the only element present in
nums after the following process terminates:
numscomprise of n elements. If
n == 1, end the process. Otherwise, create a new 0-indexed integer array
n - 1.
- For each index i, where
0 <= i < n - 1, assign the value of
(nums[i] + nums[i+1]) % 10, where
%denotes modulo operator.
- Replace the array
- Repeat the entire process starting from step 1.
Return the triangular sum of
1 2 3 4 5 \ / \ / \ / \ / 3 5 7 9 \ / \ / \ / 8 2 6 \ / \ / 0 8 \ / 8 Input: nums = [1,2,3,4,5] Output: 8 Explanation: The above diagram depicts the process from which we obtain the triangular sum of the array.
Input: nums =  Output: 5 Explanation: Since there is only one element in nums, the triangular sum is the value of that element itself.
1 <= nums.length <= 1000
0 <= nums[i] <= 9
