Problem Statement We have given binary string str, and we require to remove minimum characters from the string such that we can place all zeros before 1. Sample Examples Input str = ‘00110100111’ Output 3 Explanation Here, we can achieve output 3 in two ways. We can either remove arr[2], arr[3], and arr[5] or arr[4], arr[6], and arr[7] from the string. Input str = ‘001101011’ Output 2 Explanation We can remove arr[4] and arr[6] to place all zeros before 1. Input str = ‘000111’ Output 0 Explanation In the given str, all ... Read More
Transmission Control Protocol comes under the fourth Layer of the Open System Interconnection model. The main purpose of TCP is to track the packets and these fields add extra information on the TCP header. The connection must be implemented before transferring the packets. Some of the errors that may arise while transferring packets are the packets may be lost, packets may replicate, and damaged. The Internet Protocol (IP) packet will follow a format called TCP segment which is composed of two parts namely the Header and data. In this article, the two fields of the TCP header namely MSS and ... Read More
Signaling system 7 is a protocol that comes under the network layer of the Open System Interconnection model. It helps the node of the network to track the transfers of messages. Message Transfer protocol is the basis and is divided into many layers according to its function. The first layer represents the setting up of the network, then the second layer take care of transmissions without any error and the third layer acts like a medium between two networks. MTP3B stands for Message Transfer Protocol broadband as it transfers multiple signals concurrently. What is MTP3? In the SS7 protocol, there ... Read More
The pyttsx3 is a Python library that provides a simple interface for using TTS synthesis. Text to Speech (TTS) converts written text to spoken words. It is mainly used to generate speech from text and customize various aspects of the speech audio. The speech output generated by the pyttsx3 library is often saved as an audio file in popular formats like MP3 or WAV. This article will discuss how we can save pyttsx3 results to MP3 or WAV files. Algorithm A general algorithm for saving the pyttsx3 result to mp3 or WAV file is as follows : Import ... Read More
MediaFire and Securesafe are storage devices used by different organizations and for personal purposes. MediaFire has been first launched in the year 2006 which provides a storage space of 10GB and later Securesafe was introduced in the year 2009 which provides 100 GB storage space. Using the Securesafe, it makes the user to access the data like pictures, videos and music very easily and securely. On the other hand, Mediafire does not provide any kind of security to the files stored. What is Mediafire? MediaFire provides a storage service in cloud-based and not physical.
