This is because generating all sequences … Read more
[Solved] Use String isEmpty to check for empty string
[ad_1] The empty string is the only empty string, so there should be no cases where string.isEmpty() does not return the same value as string == “”.

[Solved] The way of thinking in multiply 2 natural numbers (problem solving”)
[ad_1] (multiply(cy, z/c) + y · (z mod c)) When c is the base of your representation (like decimal), then this is how multiplication can be done “manually”. It’s the “shift and add” method. In c-base cy is a single shift of y to the left (i.e. adding a zero at the right); and z/c … Read more

[ad_1] your getRate method returns zero when you define rate_Nok_Eur = getRate(‘NOK’, ‘EUR’), so amount_nok / rate_Nok_Eur will gave you the error, you need to specify the case when you have getRate(‘NOK’, ‘EUR’) [ad_2] solved Need help solving “ZeroDivisionError: division by zero”
[Solved] Save a ” with variable in a text file php
[ad_1] I want to save “$my variable” in the file If I understand you correctly, you want the resulting output to include quotes? You’d need to include the quotes in the value being saved.

[Solved] “How can I conditionally format the letters in a datatable?
[ad_1] Currently, color = ifelse(‘VARIACION'< -0,’#ed1c16′,’#0ca649’) is evaluating whether the string VARIACION is less than 0. While that is not a particularly meaningful question, R does indeed evaluates that to FALSE (in all your cases) and thus prints things in green as a result. More generally, you do not want to use ifelse() in this … Read more

[Solved] What is wrong with my “summarize” command?
