Here’s one way: public static void main(String[] args) { String s = “abc,xyz,lmn,ijk”; char[] ch = s.toCharArray(); int counter = 0; int place = 2; for (int i = 0; i < ch.length-2; i++) { if(ch[i] == ‘,’) { counter++; } if(counter == place && ch[i] != ‘,’) { System.out.print(ch[i]); } } } It prints … Read more
The question is a bit too broad to answer it here. But Jonas Bonér, the creator of Akka, explores the relationship between Microservices and Reactive Systems in his free ebook “Reactive Microservices Architecture“, why don’t you read that for a start. Akka is a library/tookit, it’s more low-level and doesn’t guide you towards using certain … Read more

strcmp & strncmp functions return 0 if strings are equal. You should do: if (strncmp(frase1, frase3, 4) == 0) … i.e.: char *str1 = “Example 1”; char *str2 = “Example 2”; char *str3 = “Some string”; char *str4 = “Example 1”; if (strncmp(str1, str2, 7) == 0) printf(“YES\n”); // “Example” <-> “Example” else printf(“NO\n”); if … Read more

When using if statements and you want to compare a result you should use == instead of =. With = you are assigning a value to a variable and == compares between to values. You can also not compare two things at the same time like: if (result = 70<=100) You need to check if … Read more
You already mentioned the solution in your question. You can use: range(0, 10) To repeat the sequence 3 times you could do: str_repeat(implode(‘ ‘,range(0, 10)).’ ‘, 3); 1 solved How to range and sequence in PHP
No. For example, take the following grammar: E -> TE’ | T E’ -> +TE’ | -TE’ | T T -> FT’ | F T’ -> *FT’ | /FT’ | F F -> cte | (E) It is the well known grammar for arithmetic expressions, written in LL(1) form. It is also a well known … Read more
Simply Math.Round(24.86) This will round you value to 25. Your own logic will be decimal d = 1.5m; decimal r = d – Math.Truncate(d); if (r > 0) r = 1 – r; decimal value = d + r; solved How to get the round off value of a decimal in C# [duplicate]
Width and precision specifiers can be replaced by an *, that makes printf look for the value in the arguments. printf(“%5.3f”, M_PI); is equivalent to printf(“%*.*f”, 5, 3, M_PI); but now 5 and 3 can be replaced with expressions calculated at runtime. The rest of your exercise should be trivial. 1 solved Make table for … Read more
Consider adding a flag to the User table that indicates if the user is a temporary user or not: alter table user add is_temp tinyint unsigned default 0 not null; This will allow a simple foreign key reference from In_Out: alter table In_Out change id User_id <Match Data Type And Nullness Here>, add constraint User_id_fk … Read more
Every integer is divisible by itself and by 1. If the integer is composite, it will have at least one other pair of divisors (which may be the same, as in the case of 4, which is divisible by 1,4 and 2,2). lim = int(math.sqrt(num)) for i in range (1, lim): if num%i==0: print(i, int(num/i)) … Read more
