JavaScript Number Pattern 59

Here`s a program that prints the above number pattern using JavaScript Programming:

example.html

Copied

<!DOCTYPE html>
<html>
 <head>
  <style>
   div{
    display: inline-block;
    text-align: center;
    width: 20px;
   }
  </style>
 </head>
<body>

<script>
var i, j, k, m, n;
var k = 6, l = 13, m = 16;
for(i=1; i<=5; i++)
{
 for(j=1; j<=5; j++)
 {
  if(i == 1)
   document.write("<div>"+ j +"</div>");
  else if(j == 5)
   document.write("<div>"+ k++ +"</div>");
  else if(i == 5)
   document.write("<div>"+ l-- +"</div>");
  else if(j == 1)
   document.write("<div>"+ m-- +"</div>"); 
  else
   document.write("&nbsp;&nbsp;&nbsp;&nbsp; ");
 }
 document.write("<br>");
}
</script>
</body>
</html>

💻 Testing the Program

When you run the above program, it will print the following output:

Output

1  2  3  4  5
16          6
15          7
14          8
13 12 11 10 9

🧠 How the Program Works

Let's break down the logic behind the code:

Variable Declaration: The program starts by declaring several variables: i, j, k, m, and n.
Variable Initialization: The variables k, l, and m are initialized to the values 6, 13, and 16, respectively.
Outer Loop (i): The outer loop runs from i = 1 to i <= 5. This loop controls the rows of the pattern.
Inner Loop (j): Inside the outer loop, there's an inner loop that runs from j = 1 to j <= 5. This loop controls the columns of the pattern within each row.
Conditional Statements: Inside the inner loop, there are several conditional statements based on the values of i and j.
1. if(i == 1): When i is 1 (first row), it prints the value of j wrapped in a <div> element.
2. else if(j == 5): When j is 5 (last column), it prints the value of k and then increments k by 1, wrapped in a <div> element.
3. else if(i == 5): When i is 5 (last row), it prints the value of l and then decrements l by 1, wrapped in a <div> element.
4. else if(j == 1): When j is 1 (first column), it prints the value of m and then decrements m by 1, wrapped in a <div> element.
5. else: For all other cases, it prints four non-breaking space characters ( ) to create spacing.
Line Break: After each row is processed, a line break (<br>) is added to move to the next line.
Result: The program generates a pattern that consists of five rows and five columns. The pattern varies based on the values of i and j as described in the conditional statements. The pattern elements are enclosed within <div> tags, and the spacing is controlled by printing non-breaking space characters or the values of k, l, and m.
Output: The resulting pattern is displayed on the webpage as a set of nested <div> elements, creating a visually interesting arrangement of numbers and spaces.

💯 Tips for Enhancement:

Explore the versatility of this pattern by adjusting its parameters. Whether you increase or decrease the size, tweak the spacing, or modify the characters used, each change opens up a world of possibilities, allowing you to customize and create your unique visual effects.
