Solution in javascript.
function staircase(n) {
// Write your code here
var line = '';
for(let i = 1; i <n +1; i++) {
line += Array(n-i).fill(' ').join('')
line += Array(i).fill('#').join('')
console.log(line)
line = ''
}
}

this for java
for(int i = 1; i <= n ; i++){
int freesSpace = n - i ;
for(int a = 1; a<=freesSpace;a++){
System.out.print(" ");
} for(int b = 1; b<=i;b++){
System.out.print("#");
}
System.out.print("\n");
}
}
and all the HackerRan Solution it is in my GitHub
github.com/Al-Amer/HackerrankJava
padStartalso can be used to solve this, for adding padding on string.developer.mozilla.org/en-US/docs/W...
Ohh! okay thanks
function staircase(n) {
// Write your code here
let string = "";
for (let j = n; j > 0; j--) {
for (let i = 1; i <= n; i++) {
if (i < j) {
string += " ";
continue;
}
string += "#";
}
if (j === 1) {
continue;
}
}
console.log(string);
}
what's the issue with this one!! However, as soon as I run the code on the console it's given me the same output as the one on HackerRank but whenever I sumbit the code through hackerRnak' website ,the compiler message is telling me back the code I wrore was wrong!!
function drawTriangle(n) {
let j = "#";
let i = 1;
let myTriangle = "";
while (i <= n) {
myTriangle += "\n" + j;
j += "#";
i++;
}
console.log(myTriangle);
}
