Apart from these, they also have applications in many standard algorithmic problems like: Matrix Multiplication, Adjacency matrix representation in graphs, Grid search problems Two – dimensional Array (2D-Array).In dynamic programming questions, multidimensional arrays are used which are used to represent the states of the problem.Another common usage is to store the images in 3D arrays. For example, storing the roll number and marks of a student can be easily done using multidimensional arrays. Multidimensional arrays are used to store the data in a tabular form.Software Engineering Interview Questions.Top 10 System Design Interview Questions and Answers.Top 20 Puzzles Commonly Asked During SDE Interviews.Commonly Asked Data Structure Interview Questions.Top 10 algorithms in Interview Questions.Top 20 Dynamic Programming Interview Questions.Top 20 Hashing Technique based Interview Questions.Top 50 Dynamic Programming (DP) Problems.Top 20 Greedy Algorithms Interview Questions.Top 100 DSA Interview Questions Topic-wise.Modifiers can change how a search is performed. The preg_match() function will tell you whether a string contains matches of a pattern. Returns a new string where matched patterns have been replaced with another string Returns the number of times the pattern was found in the string, which may also be 0 Returns 1 if the pattern was found in the string and 0 if not Preg_match(), preg_match_all() and preg_replace() functions are some of the PHP provides a variety of functions that allow you to use regular expressions. ![]() Slashes it is convenient to choose other delimiters such as # or ~.
