Write a method that will display numbers from 1 to n, 7 numbers per line. The numbers are separated by one space. The method header is as follows: public static void displayNumber(int n) {

Question

Anyone can help with that please

Answer 1

Hi there! I hope this helps:

//Method header from the question

public static void displayNumber(int n) {

//Empty string for us to build and then display later

var str = "";

//here's a for loop that will iterate n times starting at 1

for(int i = 1; i <= n; i++){

//First we will build our string here

str = str + i + " ";

//If the current number is divisible by 7 then we need to move to the next line with a new line character

if(i % 7 == 0){

str = str + "\n";

}

}

//Then we've got our built string! if n is 5 it should be: "1 2 3 4 5 " now we just need to log it to the console.

//It wasn't specified where it needs to be displayed so I'm assuming it's the console.

console.log(str);

}
