It's time to put up the Christmas tree at home! 🎄 But this year we want it to be special. We're going to create a function that receives the height of the tree (a positive integer between 1 and 100) and a special character to decorate it.
The function should return a string that represents the Christmas tree, constructed as follows:
- The tree is made up of triangles of special characters.
- The spaces on the sides of the tree are represented with underscores _.
- All trees have a trunk of two lines, represented by the # character.
- The tree should always have the same length on each side.
- You must ensure the tree has the correct shape using line breaks \n for each line.
Make sure to use line breaks \n at the end of each line, except for the last one.
const tree01 = createXmasTree(5, '*')
console.log(tree01)
// Expected result:
/*

__*****__

const tree02 = createXmasTree(3, '+')
console.log(tree02)
// Expected result:
/*

const tree03 = createXmasTree(6, '@')
