Apart from the fact that prompt() function does not exist in nodejs, 0 is technically a perfect square and except if it was stated explicitly to ignore zero, i don't think that condition should be there. it would be safe to consider positive numbers as the only possible numbers and Incase if the testcase has a test for big integers, that condition at line 8 will fail. I would suggest you do something like this If (sqrt(x) % 1 === 0n) or in es2020 Number.isInteger(sqrt (x)) note: sqrt is from Math I'm sure there have to be a faster way for big integer operations too like right shift to 5n >> 5n but that wouldn't be necessary I guess

Could you please describe what the code is supposed to do? According to the error message, we can't use prompt() in the node.js script. If it is a sololearn code task, use the given code to get input.

Worked. Thx for all) Prompt - is a title of function: const prompt = (function() { const lines = require('fs').readFileSync(0, 'utf8').split('\n') return function() { if (lines.length > 0) return lines.shift() const error = Error('EOF when reading a line') error.name = 'EOFError' throw error } })()

prompt function doesn't works in Node js use readLine function

let x = Number(prompt()) let y = Number(prompt()) let a = '' for(x; x <= y; x++){ if (Number.isInteger(Math.sqrt(x))){ a = a + " " + x } } console.log(a)

Use Web playground's JavaScript tab for running JS code..

This is a task from another course. Machine translate: "Input data Integers a and b are entered. It is guaranteed that a does not exceed b. Output Print all numbers on the segment from a to b that are perfect squares. If there are no such numbers, then nothing needs to be output."
