The sum of the series is the value of all terms in the given series added together in a particular pattern. Here given pattern is in the form of the: ∑ (n*(n+1)*(n+2)) as (n*(n+1)*(n+2)) is the last term in the given pattern. The following article discusses 3 approaches in detail ... Read More

Substrings are the subsets or sequences of contiguous characters of a string. Now, in this problem, we need to find the number of substrings with the frequency of at most one character as odd. Let us see how we should proceed to solve this problem. Let’s try to understand this ... Read More

A numerical string is used to store a value of a number if we want to store a huge valued integer. As we know, we can not store a number greater than 32 bits in the computer with its datatype as int. So to avoid the overflowing condition, in this ... Read More

There are 26 total different alphabets exist in the English language. If we want to change the alphabet characters into numerical values then we need to assign the alphabet, values between 1 to 26 only. Now, in this problem, we need to Maximize the String value by assigning values ... Read More

Concatenation is an operator which is used to join one or more than one string to originate a new string which would be a combination of strings that were used to generate it with the help of concatenation. In the following article, we will take the uppercase letters only in ... Read More

In standard ASCII-encoded data, there are unique values for 256 alphabetic, numeric, or special additional characters and control codes. Problem Statement Now, in this problem, ... Read More

Hamming distance between two strings of equal length is the number of all the positions at which a different value exists at the corresponding position of the other string. We can understand this with an example given below − S = “ramanisgoing” T = “dishaisgoing” Here, 5 is the ... Read More

Lexicographic means the algorithm by using which we can arrange given words in alphabetical order, the same concept which is used in dictionaries. The largest possible string that we would get by merging two strings taking one-character element at a time so that the order is lexicographic can be obtained ... Read More

The arrays of strings are a 2-dimensional array that stores characters in it. In C++ language we have an inbuilt function, with syntax − Syntax swap (first_datatype, second_datatype) which is used to perform swap operations on two elements, that is, exchange the values they carry. In the ... Read More

A binary string is a string that only has two characters, usually the numbers 0 and 1, and it represents a series of binary digits. Problem Statement Now, in this problem, we are given a binary string comprising zeros and ones. We have two conditions to keep in mind while ... Read More
