The aim of this article is to implement a program maximum count of characters that can replace? by at most A 0s and B 1s with no adjacent duplicates. Given a couple of integers A and B, both of which that represent the number of 0s and 1s that are accessible, and a string Str with only the special characters "*" and "?" The aim is to determine the greatest number of characters that may be used in the '?' position without causing any neighboring characters to be identical. Example 1 Let us give the input string str = ... Read More

The aim of this article is to implement a program to Position the leftmost set bit in a given binary string where all 1s appear at the end. A string of bits is known as a binary string. A binary string is utilized for storing non-traditional data, such as images, as opposed to a character string, which typically holds text data. The quantity of bytes in a binary string determines its length. Binary data, or data that is portrayed in a binary (base-2) version instead of a text (base-10) format, is stored in binary string variables in computer programming. ... Read More

The aim of this article is to implement a program to obtain the Lexicographically largest string formed by choosing words from a given Sentence as per given pattern. As we know, a string is a group of characters that ends with the null character "\0" in C programming. Characters from the C String are kept in a character array. The main difference between A string and a character array is that a C string differs from a character array in that it ends with the distinctive character "\0." Example 1 Input: S = “slow and steady”, B = “sdfh” ... Read More

The aim of this article is to implement a program to find the count of alphabetic and alphanumeric strings from a given array of strings. As we know, a string is a group of characters that ends with the null character "\0" in C programming. Characters from the C string are kept in a character array. A C string differs from a character array in that it ends with the distinctive character "\0." Input arr[] = {“snmd”, “nej7dnr”, “snmd”, “dltmdj”, “lbwm2p6”} Output 3 2 “snmd”: 2 “nej7dnr”: 1 “dltmdj”: 1 “lbwn2p6”: 1 Explanation The strings ... Read More

The aim of this article is to implement a program to obtain the count of sum of “10” subsequences for each 1 in string with A 1s, B 10s and C 0s. Example Let us take the Input: A = 1, B = 2, C = 3 Output obtained here is : 14 Explanation A = 1 denotes. There is a single "1" string, B = 2 denotes, there is a pair of "10" strings, and C = 3 denotes, there is a trio of "0" strings. The string that results from concatenation is "11010000". Five ...

The aim of this article is to implement a program to convert a string Str1 to Str2 by moving B to right and A to left without crossover. As we know, a string is a group of characters that ends with the null character "\0" in C programming. Characters from the C String are kept in a character array. A C string differs from a character array in that it ends with the distinctive character "\0". Example Let us take the input strings, str1 = “#B#A#”, and str2 = “##BA#” Output obtained here is: Yes Explanation − 'B' ... Read More

The aim of this article is to implement a program to minimize a given number by swapping adjacent digits with odd differences. The goal is to determine the lowest amount that can be created from a string of size N indicating an integer using only the characters '1', '2', and '3' by exchanging adjacent characters any number of times. As we all know, a string is a group of characters that ends with the null character "0" in C programming. Characters from the C String are kept in a character array. A C string differs from a character array in ... Read More

The aim of this article is to implement a program to check if a given String is K-periodic for all K in range [1, N]. The aim is to determine whether the supplied string is K-periodic provided the string s and the integer K. If a string repeats the sub-string str[0... k-1], it is said to be k-periodic; for example, the string "ababab" is 2 periods long. Print Yes if the supplied string is k-periodic; otherwise, print No. If a character string can be created by concatenating at least one repeats from another string of length k, it is said ...

Problems involving grids and matrices are mostly solved using either BFS or DFS traversal algorithms. Taking a look into the first one, Breadth First Traversal − BFS or Breadth First Traversal is an algorithm for searching a tree or a graph data structure. It starts at the root node and explores all the nodes at the present level before moving on to the next level. Algorithm procedure BFS(G, root) is let Q be a queue label root as explored Q.enqueue(root) while Q is not empty do ... Read More

Reducing an array to a single element by repeatedly removing element is done by the following criteria − Select indices i and j such that i < j and arr[i] < arr[j] and convert one of the two elements to 0. Problem Statement Given an array arr[] containing positive integers. Find if the array can be reduced to a single element by repeatedly removing an element from any increasing pair. If possible return true along with the indices chosen and the index of the element that is removed. Sample Example 1 Input arr[] = {5, 7, 10, 2, 4, ... Read More
