Two pointer approach: This is an iterative approach of problem solving which involve two pointers. We can solve several interview problems in array, linked list and string using this approach. Here are two varition of this approach : Two-pointer from the same side (Sliding Window). Two-po...
Assume that you are given a task to find a pair in an array that sums to S. Whenever I encounter problems around this line, the first approach that I can think of is theTwo-pointer approach. The reason behind that is it's super easy to understand and implement. How sorted array work?
Two-pointer approach: We use two pointers (left and right) that start at the beginning and end of the array, respectively. These pointers move towards the center. At each step, we calculate whether the left or right side has a lower height. We only calculate trapped water on the side th...
I didn't have time to cover what those specific "properties" are to qualify the usage of the two-pointer approach, but I'm gonna do that in this article, by showing, in a quite general way, what kinds of objective functions are suitable for the two-pointer approach....

In twoDimArrayDemoPtrVer.c you see two ways of passing 2-D array to a function. In first function array_of_arrays_ver array of arrays approach is used, while is second function ptr_to_array_ver pointer to array approach is used. ...
In this C program, the functionmax()is defined. It accepts twoC strings, str1, and str2, as input arguments and uses thestrcmp()function to return the greater of the two strings. The strings are compared according to the ASCII values. The larger string is returned as a pointer by the...
The main contributions of the presented approach are: (i) the driving style recognition within each of urban, rural and highway environments as well as in the case of switching among them; (ii) the two-layer pointer, which allows us to incorporate the information from continuous data into ...
the same video input and tunerfrequency. V4L and earlier versions of V4L2 used the same device nameand minor number for video capturing and overlay, but different onesfor VBI. Experience showed this approach has several problems[3], and to make things worse the V4L videodev moduleused to proh...
