If you remember back to previous challenges like Right-Align and Toggle Case, we were looking at how to format strings, in preparation for a future challenge

Let's have a look at another such string formatting challenge this week - how to format text into a pyramid/triangle shape

You should create a function that takes 5 parameters:

sentence: the string to format
initialPadding: the starting left padding for each line
paddingChange: the amount the padding changes each line
leftWordDec: the reduction in the number of words at the start of the sentence each line
rightWordDec: the reduction in the number of words at the end of the sentence each line

For this challenge, you can assume each word is separated by a single space - there will be no punctuation symbols etc

Let's look at some example function calls, with explanations underneath too:

sentence = "Insanity is doing the same thing over and over again and expecting different results"
inversePyramid(sentence, 0, 0, 1, 1)

Insanity is doing the same thing over and over again and expecting different results
is doing the same thing over and over again and expecting different
doing the same thing over and over again and expecting
the same thing over and over again and
same thing over and over again
thing over and over
over and

Note: there is 0 padding from the left, 0 padding increment and each iteration, 1 word is cut from both the start and end of the sentence

inversePyramid(sentence, 5, 3, 2, 1)

Insanity is doing the same thing over and over again and expecting different results
        doing the same thing over and over again and expecting different
           same thing over and over again and expecting
              over and over again and
                 over again
                
Likewise, here we see an initial left padding of 5 spaces with increments by 3 each line, 2 words are cut from the start of the sentence each line, while 1 is cut from the end

For your program, you should paste the output of multiple function calls one after another - for example, suppose our function calls were:

Then our output would be:

We are what we repeatedly do excellence then is not an act but a habit
  are what we repeatedly do excellence then is not an act but a
   what we repeatedly do excellence then is not an act but
    we repeatedly do excellence then is not an act
     repeatedly do excellence then is not an
      do excellence then is not
       excellence then is
        then

We are what we repeatedly do excellence then is not an act but a habit
                   We are what we repeatedly do excellence then is not an act but a
                  We are what we repeatedly do excellence then is not an act but
                 We are what we repeatedly do excellence then is not an act
                We are what we repeatedly do excellence then is not an
               We are what we repeatedly do excellence then is not
              We are what we repeatedly do excellence then is
             We are what we repeatedly do excellence then
            We are what we repeatedly do excellence
           We are what we repeatedly do
          We are what we repeatedly
         We are what we
        We are what
       We are
      We

We are what we repeatedly do excellence then is not an act but a habit
we repeatedly do excellence then is not an act but a habit
excellence then is not an act but a habit
not an act but a habit
but a habit

Note: new lines separating each function call are allowed in the output - any right (trailing) spaces will be trimmed when the site marks the answer, so whether you keep them or not is not important

For your answer, you should use the following sentence with the 6 functions calls below:

Good luck - when you think you have it, paste your answer below:
