JavaScript: Find two elements of the array such that their absolute difference is not greater than a given integer but is as close to the said integer

JavaScript Basic: Exercise-104 with Solution

Write a JavaScript program to find two elements of the array such that their absolute difference is not greater than a given integer but is as close to the said integer.

Sample Solution:

HTML Code:

<!DOCTYPE html>
<html>
<head>
  <meta charset="utf-8">
  <meta name="viewport" content="width=device-width">
  <title> Find two elements of the array such that their absolute difference is not greater than a given integer but is as close to the said integer</title>
</head>
<body>

</body>
</html>

JavaScript Code:

function different_values(ara, n) {
    var max_val = -1;
    for (var i = 0; i < ara.length; i++) {
        for (var j = i + 1; j < ara.length; j++) {
            var x = Math.abs(ara[i] - ara[j]);
            if (x <= n) {
                max_val = Math.max(max_val, x)
            }
        }
    }
    return max_val
}
console.log(different_values([12, 10, 33, 34], 10));
console.log(different_values([12, 10, 33, 34], 24));
console.log(different_values([12, 10, 33, 44], 40));

Sample Output:

2
24
34

ES6 Version:

    let max_val = -1;
    for (let i = 0; i < ara.length; i++) {
        for (let j = i + 1; j < ara.length; j++) {
            const x = Math.abs(ara[i] - ara[j]);
            if (x <= n) {
                max_val = Math.max(max_val, x)
            }
        }
    }
    return max_val
}
console.log(different_values([12, 10, 33, 34], 10));
console.log(different_values([12, 10, 33, 34], 24));
console.log(different_values([12, 10, 33, 44], 40));

JavaScript: Tips of the Day

Checks if a string is an anagram of another string (case-insensitive, ignores spaces, punctuation and special characters)

Example:

const isAnagram = (str1, str2) => {
  const normalize = str =>
    str
      .toLowerCase()
      .replace(/[^a-z0-9]/gi, '')
      .split('')
      .sort()
      .join('');
  return normalize(str1) === normalize(str2);
};
console.log(isAnagram('iceman', 'cinema')); // true

Output:

true
