Reverse Individual Words With O(1) Extra Space
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 MoreRearrange the given string such that all Prime Multiple indexes have Same Character
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 MoreMinimum Number of Adjacent Awaps to Convert a String into its given Anagram
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 MoreMake Given Binary Strings Equal by Replacing Two Consecutive 0s with Single1 Repeatedly
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 MoreFind distinct characters in distinct substrings of a string
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 MoreCount of non-overlapping sub-strings "101" and "010" in the given binary string
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 MoreCheck if a given string can be formed by two other strings or their permutations
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 MoreCase-specific sorting of strings
Strings are the storage elements for storing different kinds of letters and symbols. It is indicative of a stream of characters in C++. Strings are denoted in double quotes or single quotes. The given input string can be comprised of both uppercase and lowercase characters. The problem statement is to change the case of the characters of the string, in such a way that the letter which was originally written in lowercase is converted into uppercase and vice versa. Some of the examples illustrating the problem statement are as follows − Sample Examples Example 1 : "AbCd" Output : bAdC ...
Read MoreThe Role of Cloud Computing in Artificial Intelligence
Introduction Even though cloud computing has been around longer than artificial intelligence, it has helped artificial intelligence development in a big way. Since cloud computing came along, there has been a huge push. Some parts of AI that have changed over time are data and data sets, processing power like GPUs, models, algorithms, and talents and abilities. This essay will examine how cloud computing has helped artificial intelligence (AI) grow. Role of Cloud Computing in Artificial Intelligence Cloud delivery models With IaaS (Infrastructure as a Service), AI experts can immediately get a fully functional computing environment without waiting for an ...
Read MoreIoT Waste Management in Smart Cities
Introduction More innovative, more efficient, and resource-saving cities are possible with the help of technology and innovation that optimizes existing processes. With a larger population comes a greater and greater quantity of garbage. As a result, there is a great need to enhance waste management practices. Most current methods of garbage collection need to be updated and result in unneeded or late pickups. The annual cost of garbage collection is 70% greater due to unnecessary pickups. How Do Cities Manage Their Waste Currently? The garbage trucks in the city take a set route to pick up and drop off residents' ...
