    3355 - Zero Array Transformation I.

    Medium

    You are given an integer array nums of length n and a 2D array queries, where <code>queriesi = l<sub>i</sub>, r<sub>i</sub></code>.

    For each queries[i]:

    • Select a subset of indices within the range <code>l<sub>i</sub>, r<sub>i</sub></code> in nums.

    • Decrement the values at the selected indices by 1.

    A Zero Array is an array where all elements are equal to 0.

    Return true if it is possible to transform nums into a Zero Array after processing all the queries sequentially, otherwise return false.

    A subset of an array is a selection of elements (possibly none) of the array.

    Example 1:

    Input: nums = 1,0,1, queries = [0,2]

    Output: true

    Explanation:

    • For i = 0:

    Example 2:

    Input: nums = 4,3,2,1, queries = [1,3,0,2]

    Output: false

    Explanation:

    • For i = 0:

    • For i = 1:

    Constraints:

    • <code>1 <= nums.length <= 10<sup>5</sup></code>

    • <code>0 <= numsi<= 10<sup>5</sup></code>

    • <code>1 <= queries.length <= 10<sup>5</sup></code>

    • queries[i].length == 2

    • <code>0 <= l<sub>i</sub><= r<sub>i</sub>< nums.length</code>
