In real-world applications like weather stations, industrial sensors, or scientific experiments, data is often stored in a 2D grid, where each element represents a measurement.

In this task, you will implement a function that finds the maximum temperature using pointer-to-pointer syntax, which helps you understand how 2D arrays are stored in memory and how to navigate them with pointers.

  1. Declare a variable maxTemp to store the maximum temperature.
  2. Initialize maxTemp with the value of the first element of the array using pointer syntax.
  3. For each element, access it using pointer syntax: *(*(arr + i) + j).
  4. Compare the accessed element with maxTemp.
  5. If the element is greater than maxTemp, update maxTemp with this new value.
  6. After all elements are processed, return maxTemp as the maximum temperature found in the grid.
