 # interns-assignments
+completed by: shatakshi shrivastava
+Project Title
+Challenge1:
+Write a program to programmatically trigger an email.
+
+The program must be able to send an email to “[email protected]”.
+
+The Subject of the email Should mention “Challenge 3 Completed”.
+
+The body of the email should contain:
+
+Your name, semester, branch, and roll number
+An image attachment. (Only images of type PNG, JPG, JPEG are allowed.)
+During the development, please use your personal email id to test the program.
+
+Deployment
+To deploy this project 
+run the following commands in the ternimal: 
+npm i 
+cd src 
+node challenge1.js
+
+challenge 2 – Palindrome Checker
+Write a program that checks whether a given string is a palindrome or not. A
+palindrome is a word, phrase, or sequence of characters that reads the same
+backwards as forward.
+
+Language:- Any (i.e. Java, C, C++, JavaScript, Python, etc.). However, preferred is Java.
+
+Your program should prompt the user to enter a string, and then it should determine and
+display whether the input string is a palindrome or not.
+
+Deployment
+To deploy this project simply run it in browser.
+
+challenge 3 – Binary Search
+Write a program that implements the binary search algorithm to search for a
+specific element in a sorted array. The program should allow the user to input a
+target element and then search for that element in the sorted array. It should
+return the index of the element if found or indicate that the element is not in
+the array.
+
+Language:- Any (i.e. Java, C, C++, JavaScript, Python, etc.). However, preferred is Java.
+Deployment
+To deploy this project simply run it in browser.
+
+Challenge 4 – String Manipulation
+Write a program that takes a sentence as input and performs the following
+operations:
+1.Count the number of words in the sentence.
+2.Reverse the order of words in the sentence.
+3.Replace all spaces with hyphens ('-').
+
+Language:- Any (i.e. Java, C, C++, JavaScript, Python, etc.). However, preferred is Java.
