for(int i=0;i<s.length();i++){
if(i==0){
ch=Character.toUpperCase(s.charAt(i));
s.replace(s.charAt(i),ch);
}
if(i!=s.length()-1){
if(s.charAt(i+1)==' '){
ch=Character.toUpperCase(s.charAt(i));
s.replace(s.charAt(i),ch);
}
}
if(s.charAt(i)==' '&&i!=s.length()-1){
ch=Character.toUpperCase(s.charAt(i+1));
s.replace(s.charAt(i+1),ch);
