bro

#

actuallythis is the question

#

but i found a online solution in just 1 line

# 
System.out.printf("%-15s%03d\n", s1, x);
#

what does this line means may u explain?

hot summit
#

and padded with spaces to fill the field if necessary

torn bloom
#

and how this line auto adds 0 befor int if it is not of 3 digit?

hot summit
#

%03d part of the format string specifies that the second argument, x, should be formatted as a decimal integer with at least three digits, padded with leading zeros!

torn bloom
#

oo still i have not studied printf

hot summit
#

goodluck!

@hot summit

#

may u explain my a ques?

hot summit
torn bloom
#

what is it trying to say i can even understand that

hot summit
torn bloom
#

from my understanding i think we should print a+2 to the power 0 to the number provided(which is n)*b

# 
for (int j = 0; j < n; j++) {
                int x = (int) Math.pow(2, j);
                s = a + x * b;
            }```

like this?
