Minimize Suffix flip to make Binary String non decreasing
In this problem, we will count the number of minimum operations required to convert string non-decreasing order by flipping the characters of the binary string. We can flip all characters of the substring starting from the \mathrm{p^{th}} index if the character at the pth index is 0 and not matching with character at the previous index, and we can count the minimum flips. Problem statement - We have given a binary string alpha. We need to count the minimum flips required to convert the binary string in increasing order. In one flip, we can select any index p ...
Read MoreMaximum point to convert string S to T by swapping adjacent characters
In this problem, we will find the maximum points while converting the string S to T according to the conditions in the problem statement. We can traverse the string S and make each character of the string S same as string T's character at the same index by maximum swaps to get maximum points. In the other approach, we will prepare a mathematical formula based on the string's observation to get the answer. Problem statement - We have given a string S and T containing the alphabetical and numeric characters. We need to count the maximum ...
Read MoreMaximum bitwise OR on of any two Substrings of given Binary String
In this problem, we need to find the maximum OR value of any two substrings of the given strings. The first approach is to find all substrings of the given binary string, take OR value of each string, and print the maximum OR value. The other approach is to take the original string as one substring and take another substring starting from left most zero to maximize the OR value. Problem statement - We have given a binary string alpha. We need to find the maximum OR value of any two substrings of the given binary ...
Read MoreCount ways to form N Sized Strings with at most two adjacent different pair
In this problem, we will count the number of binary strings of size N, containing at most 2 adjacent distinct pair of characters. It means the string should contain, at most, 2 '01' 0r '10' pairs. The first approach is that generate all binary strings, and if any binary string contains less than or equal to 2 distinct pairs of characters, include its count in the result. For the optimal solution, we can count a number of binary strings containing 0, 1, and 2 adjacent different pairs and sum them. Problem statement - We have given a positive ...
Read MoreCount Substrings with at least one occurrence of first K alphabet
In this problem, we need to count substrings containing a minimum 1 occurrence of all K characters. Here, we will use two different approaches to solve the problem. The first approach takes all substrings of the given string, checks whether the substring contains all K characters, and counts such substrings containing all K characters. The second approach uses the sliding window technique to solve the problem. Problem statement - We have given a string alpha containing N characters. Also, we have given K, representing the string containing multiple occurrences of only the first K alphabetical characters. We ...
Read MoreCount of Strings of Array having given prefixes for Q query
In this problem, we will count the number of strings containing query string as a prefix for each query string. We can traverse the list of query strings, and for each query, we can find a number of strings containing it as a prefix. Also, we can use the trie data structure to solve the problem. Problem statement – We have given an strs[] and queStr[] string array containing N and Q strings, respectively. We need to count the number of strings from the Strs[] array containing the queStr[i] string as a prefix for each string of ...
Read MoreCheck if string S can be converted to T by incrementing characters
In this problem, we will check whether it is possible to convert string S to T by incrementing the characters of S only once according to the given condition. Here, we can increment any characters by 'I' only once. So, If we need to increment any other character by 'I' times, the value of K should be greater than 26 + I. Problem statement – We have given a string S, T, and positive integer K. We need to convert the string S to T by following the rules below. We can take ...
Read MoreExplain about Varargs in java?
A method can accept a variable number of parameters thanks to a Java feature called variable arguments, or varargs. This can be helpful for methods that need to be able to manage an unknown or variable number of inputs. We had two ways to handle methods that needed to take a variable number of arguments prior to introduction of varargs in Java 5. One way was to use overloaded methods. The method has to be developed in numerous iterations, each with a different number of arguments. If the process had many arguments, it might become complicated and challenging ...
Read MoreEssential Java Tips and Tricks for Programmers
Java is a powerful and versatile programming language. It is used in various applications. It's known for its reliability, portability, and safety, which makes it a famous desire for developers. Java is likewise exceptionally easy to analyze, which makes it a terrific desire for novices. However, it's critical to remember that simplicity might operate as an obstacle. If you're not mindful, you could be caught by Java's accessibility and neglect to explore the unique opportunities the language offers. Let's have a look at some tips to assist you develop as a Java developer and improve your language proficiency. Tip 1: ...
Read MoreEscape sequences in Java
Escape sequences are a unique kind of character that are used to indicate a different way of interpreting a group of characters. An escape sequence in Java is a character that is preceded by a backslash (). An escape sequence is treated by the Java compiler as a single character with unique meaning. Java frequently employs the following escape sequences: \t: Adds a new tab : Adds a new line \r: Adds a carriage return ': Adds a single quote ": Adds a double quote \: Adds a backslash These escape sequences can be used to control the ...
