value in array element

set to j=0
count--;//System.out.println(count); //count is
decremented

have reversed the string and store it in string (strn),but not the
first word of string
if(count==0){ //if count
is zero then

added to string

m is initialised to 0 and upto i
strn+=str.charAt(m); //store
each char in the string (strn)
}
i=-1;
}

space at first position)
n--;
}
