Guys, can we use the string function 'replace' while attempting programs? For eg. in questions like Q6 in 2006 board paper. That is the easiest way but the prog. becomes too short so...what to do?

Write the following code without break or continue:
char ch=inp.next.charAt(0);
int let=1;
while(ch!='&')
{
ch=inp.next().charAt(0);
if(ch=='@')
break;
if(ch==' ')
continue;
let++;
}
