Hexadecagonal numbers are the numbers that represent a hexadecagon. Hexadecagon is a polygon which consists of 16 sides. A Centred Hexadecagonal number is the number represented by a dot in the centre and other dots surrounding it in the successive hexadecagonal layers i.e. 16 sided polygon. We can understand the centred hexadecagonal number better with the below figures. There is a single dot in the centre for the first centred hexadecagon number. So the first centred hexadecagonal number will be 1. There is a single dot followed by a hexadecagon surrounding it in the next centred hexadecagon number. ... Read More

A C++ string is a collection of characters forming words. It may contains letters, numbers and even special characters. The sentences of a string can be clubbed together in different ways to form different types of representations. The camel case of a string denotes the string in such a way that the following two properties are maintained − The words are joined together, there is no space character. Every word has the first letter stored in upper case. Thereby, the upper case letters in this form of representation can be used to segregate the different words. This type ... Read More

A string may be composed of several words. Every word in a C++ string may contain letters, numbers or special symbols. Strings are considered to be storage elements for these kind of characters. Each word is separated by a space character. Each word also forms a string of characters. Reverse of any string in C++ is the string follows the following points − It is formed by taking characters from the end towards the beginning. The length of the original string remains unchanged. The order of occurrence of characters in a string can be reversed easily by swapping ... Read More

A string is a sequence of characters, numbers, Alphanumeric characters and special characters. The length of a string is the number of characters that are present in it. A prime number is the number which is divisible by 1 and the number itself. In this artice, we are given a sample input string of length n. We are going to develop a code where the idea is to substitute the same character at any position p, such that the the characters at positions ranging from 1 to n/p should coincide. Some of the examples illustrating the problem statement ... Read More

Every string is formed by a sequence of characters arranged in an order. The string may be composed of letters, number or even special characters. An anagram of any input string, is the string with a random permutation of characters. This implies, that when the order of the characters is rearranged, an anagram of the string is obtained. The respective counts of the characters should also remain the same in anagrams. Two anagram strings have the following implications − Both of them contains the same set of characters. Both of them may have a different permutation of characters ... Read More

A binary string in any programming language is a collection of characters, 0 and 1. At every stage, the binary string follows the approach that the string can contain only these two characters. Consecutive characters in strings are the characters such that the difference in indices is 1. Let us consider two indices, i and j , they are said to be consecutive, if |j-i| = 1. Two strings in C++ are said to be equivalent if − The corresponding characters in both the strings are same. The length of the strings are equal as well as the characters ... Read More

A string is a sequence of characters, numbers and special characters. A string may contain multiple substrings. A substring of a given string is any sequence of characters taken in order. It must satisfy the following properties All the characters should be taken from the input string The indexes taken from the original string should be contiguous. The characters can’t be skipped from between. It may eliminate characters from the original string. All the characters taken from a particular string should be consecutive in nature. However, each substring may be composed of same or different characters. In this ... Read More

A binary string is a sequence of characters comprising of 0’s and 1’s only. A binary string can’t contain any other character. Some of the examples of binary strings are “0000”, ”01010” or “11111” A substring of a given string is a sequence of characters taken in order. A string may contain multiple substrings. Non-overlapping strings are the strings where the indices of any two found substrings should not collide with each other. This implies that for any two substrings substr1[a..b] and substr2[c..d], either of the following, bd should be true. The problem statement involves the computation of the ... Read More

A string is a continuous stream of characters, numbers. It may even contain special characters. An string can be composed of multiple sub-strings, also referred by words. A permutation of a string is another string composed of the same set of characters, possibly arranged in a different order. It can basically be considered as a reordering of the string letters. For instance, abcd and badc are the permutations of the same string. Sample Examples Example 1 : str : “Permutation” arr : {“repuio”, ”mat”, “mtatn”, ”mutate”} Output :Yes The input string “Permutation” can be formed from the pair strings at ... Read More

Cloud Computing will increase creativity and enhance service provision in the public and private sectors of developing countries. Gaining access to data and processing resources on demand that can be scaled up to improve efficiency. Cloud computing is effective because it can be accessed by anybody, anywhere in the world, and with access to the internet, such as governments in underdeveloped countries, which often have limited resources, can benefit greatly from cloud computing. Automotive With the automotive cloud, car companies can store their inventory and other data in one place that is easy to get to. The automotive industry depends ... Read More
