<p>You want to schedule a list of jobs in <code>d</code> days. Jobs are dependent (i.e To work on the <code>i<sup>th</sup></code> job, you have to finish all the jobs <code>j</code> where <code>0 <= j < i</code>).</p>
 | 
						|
 | 
						|
<p>You have to finish <strong>at least</strong> one task every day. The difficulty of a job schedule is the sum of difficulties of each day of the <code>d</code> days. The difficulty of a day is the maximum difficulty of a job done on that day.</p>
 | 
						|
 | 
						|
<p>You are given an integer array <code>jobDifficulty</code> and an integer <code>d</code>. The difficulty of the <code>i<sup>th</sup></code> job is <code>jobDifficulty[i]</code>.</p>
 | 
						|
 | 
						|
<p>Return <em>the minimum difficulty of a job schedule</em>. If you cannot find a schedule for the jobs return <code>-1</code>.</p>
 | 
						|

<pre>
 | 
						|
<strong>Input:</strong> jobDifficulty = [6,5,4,3,2,1], d = 2
 | 
						|
<strong>Output:</strong> 7
 | 
						|
<strong>Explanation:</strong> First day you can finish the first 5 jobs, total difficulty = 6.
 | 
						|
Second day you can finish the last job, total difficulty = 1.
 | 
						|
The difficulty of the schedule = 6 + 1 = 7 
 | 
						|

<p><strong class="example">Example 2:</strong></p>
 | 
						|
 | 
						|
<pre>
 | 
						|
<strong>Input:</strong> jobDifficulty = [9,9,9], d = 4
 | 
						|
<strong>Output:</strong> -1
 | 
						|
<strong>Explanation:</strong> If you finish a job per day you will still have a free day. you cannot find a schedule for the given jobs.

<p><strong class="example">Example 3:</strong></p>
 | 
						|
 | 
						|
<pre>
 | 
						|
<strong>Input:</strong> jobDifficulty = [1,1,1], d = 3
 | 
						|
<strong>Output:</strong> 3
 | 
						|
<strong>Explanation:</strong> The schedule is one job per day. total difficulty will be 3.
