Symbols.java

/* There is a problem with your keyboard: it randomly writes symbols when you are typing a text. You need to clean up the text by removing all symbols.
Take a text that includes some random symbols and translate it into a text that has none of them. The resulting text should only include letters and numbers.
Sample Input: 
#l$e%ts go @an#d@@ g***et #l#unch$$$
Sample Output: 
lets go and get lunch
