What is the empirical formula for the molecule?
A Molecule has been identified that contains three elements: carbon, hydrogen and oxygen. When the molecule is broken down, the mass percentages are:
C= 40.9%
H= 4.58%
O= 54.5%
Assume that Q= (1/3)L3 -10L2 -21L

Write a program to take a String as input then display the words in one column, number of characters in each word in second column and the first letter of each word in third column with appropriate heading.
For example:
Enter a String
Hello world
Words Length First Letter
Hello 5 H
world 5 w
for(i=0;i<s.lastIndexOf(' ');i++) {
c = s.charAt(i);
if(c ==' ')
s1=s1+s.charAt(i+1)+" ";
} //Use this code for first letter
for(i=0;i<s.length();i++) {
c = s.charAt(i);
if (c != ' ')
n = n+c;
else {
System.out.println(n+...);
} //Use this code for display words and its number of characters
