In this article we will discuss about how to find maximum number of squares that can fit in a right-angle Isosceles Triangle using Java programming language.

## Java Program to Find Maximum Number of Squares That Can Fit in a Right-Angle Isosceles Triangle

Before jumping into the program directly, let’s first know how can we find maximum number of squares that can fit in a right-angle isosceles triangle.

**Explanation:**

Let us consider a right angle triangle with height 'h'. If we remove squares of 's' size from the triangle’s base, we are left with a new right angle triangle of height (h-s) f(h,s) = h/s – 1 + f(h-s,s)

**Example:**

When h=6 and s=2

f(6,2) = 6/2 – 1 + f(6-2,4)

=> 4-1+4/4-1 = 3

Let’s see different ways to find maximum number of squares that can fit in a right-angle Isosceles Triangle.

### Method-1: Java Program to Find Maximum Number of Squares That Can Fit in a Right-Angle Isosceles Triangle By Using Static Value

**Approach:**

- Declare the value for height of the triangle and square side.
- Then call the
`maxSquare()`

method by passing both value as parameter. - In this method the number of squares that can be fit will be calculated by the formula
`(h/s-1)*(h/s)/2`

- Then print the result.

**Program:**

public class Main { public static void main(String[] args) { // Static values for the side of the triangle and the side of the square int height = 6, square = 2; System.out.println("The number of squares which can be fit into the triangle are: "+maxSquare(height,square)); } // Function that uses recursion to find out the number of squares // which can fit inside the triangle static int maxSquare(int h, int s) { return (h/s-1)*(h/s)/2; } }

Output: The number of squares which can be fit into the triangle are: 3

### Method-2: Java Program to Find Maximum Number of Squares That Can Fit in a Right-Angle Isosceles Triangle By Using User Input Value

**Approach:**

- Take user input for the value for height of the triangle and square side.
- Then call the
`maxSquare()`

method by passing both value as parameter. - In this method the number of squares that can be fit will be calculated by the formula
`(h/s-1)*(h/s)/2`

- Then print the result.

**Program:**

import java.util.Scanner; public class Main { public static void main(String[] args) { Scanner scan = new Scanner(System.in); // Asking the user for the side of the triangle and the side of the square System.out.println("Enter the side of the triangle and side of the square"); int height = scan.nextInt(), square = scan.nextInt(); System.out.println("The number of squares that can be fit into the triangle are - "+maxSquare(height,square)); } // Function that uses recursion to find out the number of squares // Which can fit inside the triangle static int maxSquare(int h, int s) { return (h/s-1)*(h/s)/2; } }

Output: Enter the side of the triangle and side of the square 9 4 The number of squares that can be fit into the triangle are - 1
