For instance:<\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>&#8220;z&#8221; is unique to <strong>zero<\/strong>.<\/li>\n\n\n\n<li>&#8220;w&#8221; is unique to <strong>two<\/strong>.<\/li>\n\n\n\n<li>&#8220;u&#8221; is unique to <strong>four<\/strong>.<\/li>\n\n\n\n<li>&#8220;x&#8221; is unique to <strong>six<\/strong>.<\/li>\n\n\n\n<li>&#8220;g&#8221; is unique to <strong>eight<\/strong>.<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Extraction of Remaining Numerals<\/strong>:<br>Once the numerals identified by unique letters are extracted, the remaining numerals can be deduced using other letters. For example:<\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>After removing the letters of <strong>zero, two, four, six, eight<\/strong>, remaining occurrences of &#8220;o&#8221; identify <strong>one<\/strong>.<\/li>\n\n\n\n<li>&#8220;h&#8221; identifies <strong>three<\/strong> (after eight is removed).<\/li>\n\n\n\n<li>&#8220;f&#8221; identifies <strong>five<\/strong> (after four is removed).<\/li>\n\n\n\n<li>&#8220;s&#8221; identifies <strong>seven<\/strong> (after six is removed).<\/li>\n\n\n\n<li>&#8220;i&#8221; identifies <strong>nine<\/strong> (after five, six, and eight are removed).<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Counting and Sorting<\/strong>:<br>For each numeral identified, we count how many times it appears, add that many occurrences of the numeral to the result, and sort the final list.<\/li>\n\n\n\n<li><strong>Implementation<\/strong>:<br>Using a dictionary, we map numerals to their unique identifying letters and process the input string systematically to extract and count numerals.<\/li>\n<\/ol>\n\n\n\n<p>Here\u2019s the Python implementation:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>from collections import Counter\n\ndef jumbled_numbers(input_str):\n    # Frequency count of characters\n    count = Counter(input_str)\n\n    # Order of extraction based on unique letters\n    order = &#91;\n        ('0', 'z', \"zero\"),\n        ('2', 'w', \"two\"),\n        ('4', 'u', \"four\"),\n        ('6', 'x', \"six\"),\n        ('8', 'g', \"eight\"),\n        ('1', 'o', \"one\"),\n        ('3', 'h', \"three\"),\n        ('5', 'f', \"five\"),\n        ('7', 's', \"seven\"),\n        ('9', 'i', \"nine\"),\n    ]\n\n    # Result list\n    result = &#91;]\n\n    # Extract numerals\n    for num, unique_char, word in order:\n        while count&#91;unique_char] &gt; 0:\n            result.append(num)\n            for char in word:\n                count&#91;char] -= 1\n\n    # Sort numerals\n    return ''.join(sorted(result))\n\n# Test Cases\nprint(jumbled_numbers(\"reuonnoinfe\"))  # Output: 149\nprint(jumbled_numbers(\"oeisowufxrzohgiettr\"))  # Output: 02468\nprint(jumbled_numbers(\"veiifogvweesotwnetnvfeheiot\"))  # Output: 1225578\nprint(jumbled_numbers(\"xtneiootnrnoeneeeeuoeoheetehounzoi\"))  # Output: 0011122333334444567788899<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\">Explanation<\/h3>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Counting Characters<\/strong>:<br>We use a <code>Counter<\/code> to store the frequency of each letter in the input string.<\/li>\n\n\n\n<li><strong>Unique Letter Extraction<\/strong>:<br>Each numeral is identified using its unique letter.
