Write a python function buildIndex(Text) that accepts Text string and returns a dictionary where each item is a key-value pair; the key is the keyword, and the value how often this keyword appears in the Text. Example: Text = "KAU is a University in Jeddah, Jeddah is a big city" after passing the Text to the function buildIndex(Text), it should return mydict ={ "KAU": 1, "is": 2, "University": 1, "a": 2, "Jeddah": 2, "big": 1, "city": 1\}
