Q1: Print a Right-Aligned Star Triangle Pattern

Problem:

Given a number n, print a right-aligned triangle of stars (*) with n rows. The stars in each row should increase from 1 to n, and the triangle should be aligned to the right side by adding spaces before the stars.

Example:

For n = 5, the output should be:

    *
   **
  ***
 ****
*****

Approach

Use an outer loop to iterate over each row.
For each row:
- Print spaces first. The number of spaces is n - (current_row + 1).
- Then print stars. The number of stars is current_row + 1.
Move to the next line after printing each row.

Example Code

function printRightAlignedTriangle(n) {
  let Stars = "";

  for (let i = 0; i < n; i++) {
      // X Loop is Responsible For Adding Spacing
      for (let x = 0; x < n - (i + 1); x++) {
         Stars += " ";
      }
     // J loop is Responsible For Adding  Start
     for (let j = 0; j < i + 1; j++) {
        Stars += "*";
     }
   Stars += "\n"; // New line after each row
 }

 return Stars;
}

console.log(printRightAlignedTriangle(5));
