Problem Statement We have given a two-dimensional array containing the pairs of starting and ending times for time intervals in the 12-hour format. Also, we have given string str in the 12-hour time format. We need to find a total number of intervals which included the time represented by str. Sample Examples Input arr[][2] = {{“12:02:AM”, “10:55:PM”}, {“12:51:AM”, “11:40:AM”}, {“01:30:AM”, “12:00:PM”}, {“11:57:PM”, “11:59:PM”}}, str = “2:30:AM” Output 3 Explanation The time “2:30:AM” intersects the first three intervals. Input arr[][2] = {{“01:02:PM”, “10:55:PM”}, {“01:30:AM”, “11:00:AM”}}, str = “11:30:PM” Output 0 Explanation The ...

Matplotlib is a popular data visualization library in Python that provides a wide range of tools for creating interactive plots and charts. One of the interactive components offered by Matplotlib is the RadioButtons widget, which allows users to select a single option from a group of mutually exclusive choices. While working with RadioButtons, you may encounter situations where you need to resize them to better fit your plot or application layout. In this article, we will explore different methods to resize Matplotlib RadioButtons. Syntax radio_buttons.ax.set_position([left, bottom, width, height]) Here, radio_buttons refers to the instance of the RadioButtons widget. ...

Problem Statement We have given string str and a binary string B. The length of both strings is equal to the N. We need to check if we can make string str palindromic by swapping the characters of it multiple times at any pair of indices that contains unequal characters in string B. Sample Examples Input str = ‘AAS’ B = ‘101’ Output ‘YES’ Explanation We can swape the str[1] and str[2] as B[1] and B[2] are not equal. The final string can be ‘ASA’. Input str = ‘AASS’ B = ‘1111’ Output ‘No’ Explanation ...

In C++, the string is a collection of various alphanumeric and special characters. We can create a string using the ‘string’ data type in C++. Problem Statement We have given a length of the string and one single character, and we require to generate a string of a given length containing the single character. In C++, we can define the string of a particular length by hard coding the values, but when we require to generate a string of different lengths and use the given character, we require to use the below approaches. Sample Examples Here are the sample ...
