tabang in Java. tabang!

sa akong nasabtan kunohay, pananglitan 5 ang length sa input. and then x is 0, nya 0 is less than 5 man, so mag.loop cya 5 times ra. hantod maabot sa 4 which is true kai 4 is less than 5 man. wa ko kasabot sa imong ipasabot nako nga it'll double the loop. hehehe. sorry noob pa tawn ta.

what is mean is that the .length() method has a loop inside it in which every increment sa i++ mo loop pud na cya number of times depende sa size/length sa string....

example
for (int i = 0; i < input.length(); i++)

lets say we input {[()]}
so input.length() = 6

inside the length() method, naa dha nag loop nga mag ihap sa characters which starts 1 to 6.

and if ato cya gamiton sa imong loop
for (int i = 0; i < mag loop 1 to 6; i++)
for (int i = 1; i < mag loop 1 to 6; i++)
for (int i = 2; i < mag loop 1 to 6; i++)
for (int i = 3; i < mag loop 1 to 6; i++)
for (int i = 4; i < mag loop 1 to 6; i++)
for (int i = 5; i < mag loop 1 to 6; i++)

nahulog nga naa kay inner loop every increment sa variable (e.g. i++)
gets mo?

ah mao diay. hehehe. pero wa raman kaha nai problema? kai same output raman japon?

[SuperStar]

ok ra man.....pero at least karon start naka optimize sa imo codes kay sa industry if mag work naka as a developer, dapat jud optimized imo codes youre dealing with thousands or millions of items or collections or lists like retrieving multiple data sa database...

maka balo ra ka ana later on

ah mao diay. hehehe. pero wa raman kaha nai problema? kai same output raman japon?

[jairoh_]

nice one. atleast di ta maihas.

for(int x=0; x<input.length();x++)

jairoh, i suggest that you should not use this style of code because it will affect the program during runtime...you'll know a lot of this during your Data Structures subject.

much better if you'll assign it to a variable, e.g. size like this

size = input.length();
for(int x=0; x<size ;x++)

well, explainan tka gamay.. if imo ukayon ang .length() method..you'll see that it will loop individually the charater...so ang mahitabo ana, every increment nimo nag loop pud ang lenght() method which will double the loop imbis dili unta dapat....nahulog nga nag nested loop naka ana imbis linear loop ra imo gibuhat

Thanks Superstar sa Tip..!

suwayi daw ni jairoh if ok ba...bag-o ra ko nahuman code...hehehe....
comment lang if asa imo wa nasabtan

simple but rock ang code...

FYI. La man ko mureklamo sa imo code bai para to kang jairoh tanan akong giingon.
Sorry kung la maklaro.

@jairoh - No probs and More power.

To further explain lang sa ... isBrace(stack.peek().toString().charAt(0))

Ang conditional statements sa java, ato lang ingnon nga TYPE dependent siya rather than EXPRESSION dependent.

So example ang if clause.

if( sampleVariable == 1 ){
}

Rather than taking "sampleVariable == 1" as an expression. Java evaluated the expression to extract the boolean value.
Moving on that note, feeding true (kanang true gyud nga dili string) to an if clause will work, but doesn't need further evaluation.
Of course, feeding an if statement false would make java continue to the else statement.

if( true ){
//kani padaganon
} else{
}

if( false ){
} else{
//kani padaganon
}

Finally, ang isBrace ni Superstar mu-return man og Boolean(true or false). Mao na ingana iyang style gigamit. Pwede ra from kani.

if (isBrace(stack.peek().toString().charAt(0)))
{
stack.pop();
}

To kani

if ( c == '(' || c == ')' ){
stack.pop();
}


Unya to further explain sa pag butang into a variable ang length sa array.
Naa man gud times, mga manghilabot ta sa array, even during a loop.
So i-save nimo ang initial value para dili maguba imong loop.

[jairoh_]

karun pako kasabot ani

if( false ){
} else{
//kani padaganon
}

if (isBrace(stack.peek().toString().charAt(0)))
{
stack.pop();
}

wa pajud ko au kasabot anang toString().charAt(0) thats why i use somewhat like this one

if ( c == '(' || c == ')' ){
stack.pop();
}

tnx dghan jud ko nakat onan
