Question

Help the lazy mountain climber. Assume that a mountain climber wants to cross a mountain range by limiting the change in elevation (i.e., the climber does not want to climb up or down more often than necessary). The elevation of the terrain is given in a m by n matrix. The climber needs to start in the first column and end in the last column. Each move can be to the right, to the right and up, or to the right and down. Construct an algorithm to determine the minimum change in altitude that is possible for crossing the mountain range. State the time efficiency of your approach

Expert Solution

Step 1

matrix are the type of data structure which is group of rows and columns.
it can be expressed in the form 2D array in terms of rows and columns.

* findmin_altitude function will find the minimum change in altitude.

* mountain_mat is used to represent the mountain matrix.
