Pyramid made out of numbers

Question

Int st=0;
int n=1;
for(int i=1;i<=5;i++,st=0){
n=1;
for(int space=1;space<=5-i;space++){
System.out.print(" ");
}
while(st != 2*i-1){
System.out.print(n);
n++;
st++;
}
System.out.println(" ");
}
}
I made this code to make a pyramid out of numbers
And the result was like this
1
1 2 3
1 2 3 4 5
How can i turn it to
1
2 3 2
3 4 5 4 3
Etc

Answer 1

for(int i=1;i<=5;i++,sp=0) {
q=i;
b=true;
for(int space=1;space<=5-i;space++) {
System.out.print(" ");
}
while(sp !=2*i-1) {
if (++sp>(2*i-1)/2) {
b=false;
}
if(b)
System.out.print(q++);
else
System.out.print(q--);
}
System.out.println(" ");
}
//Check this with your code for changes..

Answer 2

I did almost done.

Answer 3

Instead of n=1, take n=i.
And if(n>2*i-1) next decrease the value so to do that use a boolean value for either increamet or decrement... Try this way.. If not work, then also I think you may get the solution idea by this....

Answer 4

you are doing q-- in else so again chance to if statement comes true..
I said about, take a boolean value b: and set to false, when q<=2*i-1 becomes false..
Then for print statement use if(b) sop(q++) else sop(q--);
If still need modifications, better to share the full code with saving in playground and share link here...

Answer 5

//rows 5 for example
int sp=0;
int q;
for(int i=1;i<=rows;i++,sp=0) {
q=i;
for(int space=1;space<=rows-i;space++) {
System.out.print(" ");
}
while(sp !=2*i-1) {
if (q<=2*i-1 ==true) {
System.out.print(q);
q++;
sp++;
}
else {
q=2*i-2;
System.out.print(q);
q--;
sp++;
}
}
System.out.println(" ");
}
}
I almost got it
But there is sth weird happing here
1
232
34543

Answer 6

I have shared the full code , i still have some issues i believe its due to the fact that i didn't use boolean correctly

Answer 7

Thx everyone i made the code and i understood which part i failed at .
