• Make all other letters in each word lowercase.
• Words are always separated by a single space.

titleCase("hello world") should return "Hello World".

assert.equal(titleCase("hello world"), "Hello World");

titleCase("the quick brown fox") should return "The Quick Brown Fox".

assert.equal(titleCase("the quick brown fox"), "The Quick Brown Fox");

titleCase("JAVASCRIPT AND PYTHON") should return "Javascript And Python".

assert.equal(titleCase("JAVASCRIPT AND PYTHON"), "Javascript And Python");

titleCase("AvOcAdO tOAst fOr brEAkfAst") should return "Avocado Toast For Breakfast".

assert.equal(titleCase("AvOcAdO tOAst fOr brEAkfAst"), "Avocado Toast For Breakfast");
