1--> Ive been trying to make a calculator app. My problem is that I want my app to ignore unnecessary repeating input by the user to avoid having this kind of repeating zeros(0) and dot(.) : 00000.003, 3..03, 3+00000.003, etc
I'm new here so I don't know what else I could experiment on.
I've tried a combination of while loop with nested ifs with some conditions like text.startsWith, .endsWith("str", ignorecase: false) something like that for my onclick buttons.
Some code suggestions is highly appreciated.
2-->Also i've been thinking if there's a series of command/code where an individual textview will be created every time characters(created by onclick buttons) formed an integer/expression/decimalnumber(etc) as well as operation(+,-,*,/)
in a way that every number and math operations are separated into textviews(for editing purposes)
I hope someone can give me an idea and codes/commands that I might try to experiment with to develop my app
<EditText
android:id="#+id/editText"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:inputType="number" />
or
In this sample code, the text in the EditText is first converted to an Int value. If the conversion fails (that is, there is no numeric value in the text box), 0 is set by default. Next, the EditText's text is replaced with the numeric value with the redundant 0's removed.
val editText: EditText = findViewById(R.id.editText)
val number: Int = editText.text.toString().toIntOrNull() ?: 0
editText.setText(number.toString())
allows only text values to be entered
val editText: EditText = findViewById(R.id.editText)
editText.filters = arrayOf(InputFilter { source, _, _, _, _, _ ->
if (source.toString().matches(Regex("[0-9]+"))) {
source
} else {
""
}
})

I am trying to create a program which will search a string for another string, and return the string directly after that string.
Use the POS function to find the substring. Give it the string to search and the string you're looking for and it will return the position it's found at:
POS( S$, T$ )
S$ is the string you're searching
T$ is the string you're looking for
Return value is the position it's found at, or 0 if not found.
The strings are treated as arrays of characters.
A$="hello"
B$=A$[3,4] ! B$ will become "ll"
C$=A$[2] ! C$ will become "ello"
To get everything following the found substring you can use something like this:
1000 DIM A$[72]
1020 A$="Hello World, & goodbye." ! String to search
1040 T$="World, " ! String to look for
1060 L=LEN(T$)
1080 PRINT A$[L+POS(A$,T$)]
1100 END
Running this should give this result:
& goodbye.

I used two IF functions to find the maximum value of a range, but return 0 if I slightly change the function by using AND function. Please help.
This works and returns an integer:
{=MAX(IF(MONTH(A58:A67)=MONTH(K50),IF(YEAR(A58:A67)=YEAR(K50),B58:B67)))}
this one always returns 0:
{=MAX(IF(AND(MONTH(A58:A67)=MONTH(K50),YEAR(A58:A67)=YEAR(K50)),B58:B67))}
Mostly one cannot using AND in array context properly.
In your example the
IF(MONTH(A58:A67)=MONTH(K50),IF(YEAR(A58:A67)=YEAR(K50),B58:B67))
evaluates to
IF({TRUE;FALSE;TRUE;FALSE;...;FALSE}, IF({FALSE;TRUE;TRUE;FALSE;...;TRUE}, {B58:B67}))
dependent on whether MONTH(A58:A67)=MONTH(K50) is TRUE or FALSE and YEAR(A58:A67)=YEAR(K50) is TRUE or FALSE.
That means if the first is TRUE then check the second and if the second also is TRUE, then take the corresponding value from array {B58:B67} into the MAX, else take FALSE, which counts 0, into the MAX.
But
IF(AND(MONTH(A58:A67)=MONTH(K50),YEAR(A58:A67)=YEAR(K50)),B58:B67)
evaluates to
IF(AND({TRUE;FALSE;TRUE;FALSE;...;FALSE},{FALSE;TRUE;TRUE;FALSE;...;TRUE}),{B58:B67})
So both the {TRUE;FALSE;...} arrays are in the AND and that will only be TRUE if there is not a single FALSE in both the arrays, else FALSE which counts 0 in the MAX.
And even if there would not be a single FALSE in both the arrays, then always the whole array B58:B67 would be the result in the MAX.

It is possible to convert a single formatted string into a tuple, for example I am trying to transform a return from a function into a tuple.
E.g:
def GCcontent(self):
"Return GC content of the sequence given"
A = self.get_secuencia().count('A')
T = self.get_secuencia().count('T')
C = self.get_secuencia().count('C')
G = self.get_secuencia().count('G')
content = '{0:.2f}%'.format((G+C)*100/(A+T+G+C))
return content
The output is:
'XX.XX%'
But what I want to get is the following output:
('XX.XX%')
Is this even possible?. I tried tuple() function but it doesn't work as expected, is there another method to achieve this?
tuple([content]) will yield a 1-element tuple whose element is the string in content, but note that when printed, it appears as
('XX.XX%',)

My Input String is in the below format :
"USA||CANADA||RUSSIA'S||AUSTRALIA"
Kindly help me to get the Output String in the below format in c# :
" 'USA','CANADA','RUSSIA''S','AUSTRALIA' "
I have tried with the following code like :
var string ="USA||CANADA||RUSSIA'S||AUSTRALIA";
string[] countries =string.Split(new string[] "||" },StringSplitOptions.RemoveEmptyEntries);
string result = "'" + string.Join("','", countries) + "'";
I am getting the output as
" 'USA','CANADA','RUSSIA'S','AUSTRALIA' "
But I want one more Apostrophe with Russia i.e Russia''s.
Please help
You can do this:
string[] countries = "USA||CANADA||RUSSIA'S||AUSTRALIA".Split(new string[] { "||" }, StringSplitOptions.RemoveEmptyEntries);
string result = "'" + string.Join("','", countries) + "'";
Update:
Use this one:
string[] countries = "USA||CANADA||RUSSIA'S||AUSTRALIA".Replace("'", "\"").Split(new string[] { "||" }, StringSplitOptions.RemoveEmptyEntries);
string result = "'" + string.Join("','", countries) + "'";
