You are given a mountain range represented by an array of length ****, where each element represents the initial altitude at that position.

• Initial Altitudes: altitude = [1, 2, 3, 2, 0]
• Starting Position: You begin at index 0.

You are given a days matrix, where each row represents a single day and each column corresponds to the amount of snowfall at that specific length (index).

• Snowfall: If the value for a day is greater than 0, the altitude at that index increases by that amount.
• Melting: If there are two consecutive days with 0 snowfall at a specific index, the snow begins to melt, and the altitude at that position decreases by 1 unit.

Example Calculation:

• Day 1: days[0] = [1, 0, 1, 2, 1]

• New Altitudes: [2, 2, 4, 4, 1] (Initial + Day 1 snow)

• Day 2: days[1] = [1, 0, 1, 1, 0]

• At index 1, there have been 2 consecutive days of 0 snowfall. Therefore, it melts by 1.

• New Altitudes: [3, 1, 5, 5, 1]

A person can only move from index to index if the altitude difference is manageable:

• This means you can only climb up 1 unit or climb down 1 unit at a time.

Find the earliest day on which the mountain range becomes passable. If there are multiple ways to pass, find the path that requires the minimum number of climbs.
