Dynamic Maze Solver

You are given an n x m grid representing a maze, where 0 represents an open cell and 1 represents a wall. In addition, you receive a list of toggle events: at each time step (starting from time 0), certain cells in the maze may change their state (from open to wall or vice versa). Each toggle event is represented as a tuple (t, r, c), which means that at time t, the cell at row r and column c toggles its state.

Objective:

Starting at cell (start_row, start_col) at time 0, determine the minimum number of time steps required to reach the destination cell (dest_row, dest_col). Movement is allowed in the four cardinal directions (up, down, left, right) and takes one time step per move. Note that at each time step, before performing your move, all toggle events scheduled for that time step are applied to the maze.

Input Parameters:

• maze: A two-dimensional list of integers (only 0s and 1s) with dimensions n x m.
• toggles: A list of tuples (t, r, c) sorted in ascending order by t, where t is the time at which the toggle occurs.
• start: A tuple (start_row, start_col) indicating your starting cell.
• destination: A tuple (dest_row, dest_col) indicating your target cell.

Output:

Return an integer representing the minimum time required to reach the destination. If it is impossible to reach the destination, return -1.

Constraints:

• 1 <= n, m <= 100
• Toggle times satisfy 0 <= t <= 10^4
• The total number of toggle events does not exceed 10^4
• The initial maze configuration and toggle events will be valid.

Task:

Write a function to compute the minimum time to reach the destination while efficiently handling the dynamic changes in the maze due to toggle events.
