Pattern Program help

[Dio1080]

Ok, I need help on a for loop nested program using for loops, I'm trying to use a patten that goes like this:
123456
12345
1234
123
12
1

but when I try it, it goes like this:
123456
12345
1234
123
12
1

This is my program:
public class Patterns{
public static void main (String [] args) {

//set up for the rows

for(int row = 7 ; row > 1; row--){

for (int num = 1; num < row; num++){

System.out.print(num);
}
System.out.println();
}

}

}


Can anybody help please? thanks

Hi,
Please use code tags while posting code.
Your desired output and program output is same ... then what is the problem ?

I'm sorry, it must have typed it wrong, this is what I'm looking for:

123456

12345

Have you written down your algorithm for this first?

[Dio1080]

algorithm? I don't think we learned that yet?

[JosAH]

algorithm? I don't think we learned that yet?

Main Entry: al·go·rithm
Pronunciation: 'al-g&-"ri-[th]&m
Function: noun
Etymology: alteration of Middle English algorisme, from Old French & Medieval
Latin; Old French, from Medieval Latin algorismus, from Arabic al-khuwArizmi,
from al-KhwArizmI fl A.D. 825 Islamic mathematician

: a procedure for solving a mathematical problem (as of finding the greatest
common divisor) in a finite number of steps that frequently involves repetition of
an operation; broadly : a step-by-step procedure for solving a problem or
accomplishing some end especially by a computer

algorithm? I don't think we learned that yet?

An algorithm is similar to a recipe - instructions on how to do a job in loads of little steps.
For example, the algorithm to boil water may be:

1. Make sure, you have a kitchen (if you don't, create one).
2. Make sure, you have a pot (if you don't, create one).
3. Make sure, you have a tap (if you don't, create one).
4. Make sure, you have a oven (if you don't, create one).
5. Go into the kitchen (may be complex, depending on your current position).
6. Get a pot out of the shelves (may be more complex, e.g. if there are doors).
7. Position the pot under the water tap (you may have to push it to one side before).
8. Turn the tap on (there are loads of different taps).
9. While the pot isn't full enough, keep checking, if the pot is full enough (you may want to take a break every time you've checked).
10. When the pot is full, turn the tap off (same issue as turning it on).
11. Lift the pot.
12. Position the pot on the oven.
13. Switch the oven on (depending on your type of oven, this could work in different ways).
14. While the water isn't boiling, check if it's boiling.

I know, that is very detailed, but that's how you have to think when writing a program. A person would understand the command "boil water", but a computer needs all of these steps.

Two questions for a mathematician and a physicist

Question 1:

There's a bunsen burner, a book of matches a water tap and an empty kettle;
how to boil water?

Both the physicist and the mathematician come up with an identical answer:
open the tap, filll the kettle, close the tap again, put the kettle on the bunsen
burner, light it using the matches and wait.

Question 2:

There's a filled kettle positioned on the bunsen burner; how to boil water?

The physicist's answer: light the burner and wait.

The mathematician's answer: empty the kettle; now the problem is reduced to
the previous question.

kind regards,

Jos ;-)

Nice one! ^^

[Ganon11]

ERP! But once the kettle is empty, there's no specific mention of a tap? Where will the mathematician get the water? And besides, there aren't any matches.

Yep, you're right (bloody nitpickers ...) I should've defined both problems in a bit
more detail; but I hope you get the idea ;-)

Wait, almost 50% of every post I've seen you make is nitpicking - you even admit so yourself on many occasions.
