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)); 

Explanation

• The outer loop runs from 0 to n - 1, representing each row.

• Spaces decrease as the row number increases.

• Stars increase by one each row.

• Using nested loops, we build the pattern string line by line.
