Question

String Slicing

Given two strings

write a JS program to slice the inputString if it includes the subString. Slice the inputString starting from the subString to the end of the inputString.

Check Whether the input string includes the substring using if condition and includes().

if the input string includes the substring then, find the index of the substring in the input string, using the indexof() and store the index in a variable.

slice the input string, using the slice() form index to the length of the input string and store in the variable slicedString. console the variable sliceString.

If the input string doesn't include the substring then else console the input string.

Input

• The first line of input contains a string inputString
• The second line of input contains a string subString

Output

• The output should be a sliced string or inputString (if the inputString does not include the subString)

Answer 1

'use strict';


process.stdin.resume();
process.stdin.setEncoding('utf-8');


let inputString = '';
let currentLine = 0;


process.stdin.on('data', inputStdin => {
 inputString += inputStdin;
});


process.stdin.on('end', _ => {
 inputString = inputString.trim().split('\n').map(string => {
 return string.trim();
 });
 
 main(); 
});


function readLine() {
 return inputString[currentLine++];
}


function main() {
 const inputString = readLine();
 const subString = readLine();


 let index = aqString.find(inputString, subString);
 if (isNaN(index) && index <= inputString.length) {
 console.log(inputString.split(index));
 }
}
