def minimumTime(grid: List[List[int]]) -> int:
"""
You are given a m x n matrix grid consisting of non-negative integers
where grid[row][col] represents the minimum time required to be able to
visit the cell (row, col), which means you can visit the cell (row, col)
only when the time you visit it is greater than or equal to grid[row][col].
You are standing in the top-left cell of the matrix in the 0th second, and
you must move to any adjacent cell in the four directions: up, down, left, and
right. Each move you make takes 1 second.
Return the minimum time required in which you can visit the bottom-right cell
of the matrix. If you cannot visit the bottom-right cell, then return -1.
Example 1:
Input: grid = [[0,1,3,2],[5,1,2,5],[4,3,8,6]]
Output: 7
Explanation: One of the paths that we can take is the following:
- at t = 0, we are on the cell (0,0).
- at t = 1, we move to the cell (0,1). It is possible because grid[0][1] <= 1.
- at t = 2, we move to the cell (1,1). It is possible because grid[1][1] <= 2.
- at t = 3, we move to the cell (1,2). It is possible because grid[1][2] <= 3.
- at t = 4, we move to the cell (1,1). It is possible because grid[1][1] <= 4.
- at t = 5, we move to the cell (1,2). It is possible because grid[1][2] <= 5.
- at t = 6, we move to the cell (1,3). It is possible because grid[1][3] <= 6.
- at t = 7, we move to the cell (2,3). It is possible because grid[2][3] <= 7.
The final time is 7. It can be shown that it is the minimum time possible.
Example 2:
Input: grid = [[0,2,4],[3,2,1],[1,0,4]]
Output: -1
Explanation: There is no path from the top left to the bottom-right cell.
Constraints:
* m == grid.length
* n == grid[i].length
* 2 <= m, n <= 1000
* 4 <= m * n <= 105
* 0 <= grid[i][j] <= 105
* grid[0][0] == 0

def findTheString(lcp: List[List[int]]) -> str:
"""
We define the lcp matrix of any 0-indexed string word of n lowercase
English letters as an n x n grid such that:
* lcp[i][j] is equal to the length of the longest common prefix between the substrings word[i,n-1] and word[j,n-1].
Given an n x n matrix lcp, return the alphabetically smallest string
word that corresponds to lcp. If there is no such string, return an empty
string.
A string a is lexicographically smaller than a string b (of the same
length) if in the first position where a and b differ, string a has a
letter that appears earlier in the alphabet than the corresponding letter in
b. For example, "aabd" is lexicographically smaller than "aaca" because
the first position they differ is at the third letter, and 'b' comes before
'c'.
Example 1:
Input: lcp = [[4,0,2,0],[0,3,0,1],[2,0,2,0],[0,1,0,1]]
Output: "abab"
Explanation: lcp corresponds to any 4 letter string with two alternating letters. The lexicographically smallest of them is "abab".
Example 2:
Input: lcp = [[4,3,2,1],[3,3,2,1],[2,2,2,1],[1,1,1,1]]
Output: "aaaa"
Explanation: lcp corresponds to any 4 letter string with a single distinct letter. The lexicographically smallest of them is "aaaa".
Example 3:
Input: lcp = [[4,3,2,1],[3,3,2,1],[2,2,2,1],[1,1,1,3]]
Output: ""
Explanation: lcp[3][3] cannot be equal to 3 since word[3,...,3] consists of only a single letter; Thus, no answer exists.
Constraints:
* 1 <= n == lcp.length == lcp[i].length <= 1000
* 0 <= lcp[i][j] <= n

def handleQuery(nums1: List[int], nums2: List[int], queries: List[List[int]]) -> List[int]:
"""
You are given two 0-indexed arrays nums1 and nums2 and a 2D array
queries of queries. There are three types of queries:
1. For a query of type 1, queries[i] = [1, l, r]. Flip the values from 0 to 1 and from 1 to 0 in nums1 from index l to index r. Both l and r are 0-indexed.
2. For a query of type 2, queries[i] = [2, p, 0]. For every index 0 <= i < n, set nums2[i] = nums2[i] + nums1[i] * p.
3. For a query of type 3, queries[i] = [3, 0, 0]. Find the sum of the elements in nums2.
Return an array containing all the answers to the third type queries.
Example 1:
Input: nums1 = [1,0,1], nums2 = [0,0,0], queries = [[1,1,1],[2,1,0],[3,0,0]]
Output: [3]
Explanation: After the first query nums1 becomes [1,1,1]. After the second query, nums2 becomes [1,1,1], so the answer to the third query is 3. Thus, [3] is returned.
Example 2:
Input: nums1 = [1], nums2 = [5], queries = [[2,0,0],[3,0,0]]
Output: [5]
Explanation: After the first query, nums2 remains [5], so the answer to the second query is 5. Thus, [5] is returned.
Constraints:
* 1 <= nums1.length,nums2.length <= 105
* nums1.length = nums2.length

def minimumScore(s: str, t: str) -> int:

You are given two strings s and t.
You are allowed to remove any number of characters from the string t.
The score of the string is 0 if no characters are removed from the string
t, otherwise:
* Let left be the minimum index among all removed characters.
* Let right be the maximum index among all removed characters.
Then the score of the string is right - left + 1.
Return the minimum possible score to make t a subsequence of s.
A subsequence of a string is a new string that is formed from the original
string by deleting some (can be none) of the characters without disturbing the
relative positions of the remaining characters. (i.e., "ace" is a
subsequence of "abcde" while "aec" is not).
Example 1:
Input: s = "abacaba", t = "bzaa"
Output: 1
Explanation: In this example, we remove the character "z" at index 1 (0-indexed).
The string t becomes "baa" which is a subsequence of the string "abacaba" and the score is 1 - 1 + 1 = 1.
It can be proven that 1 is the minimum score that we can achieve.
Example 2:
Input: s = "cde", t = "xyz"
Output: 3
Explanation: In this example, we remove characters "x", "y" and "z" at indices 0, 1, and 2 (0-indexed).
The string t becomes "" which is a subsequence of the string "cde" and the score is 2 - 0 + 1 = 3.
It can be proven that 3 is the minimum score that we can achieve.
