Strobogrammatic Number - LeetCode

WebMar 9, 2024 · Time Complexity For all n digits, we have 5 digits to chose from, but in the above code, we start from both the extreme positions and move inwards. Hence time complexity is O(5^(N/2)). WebA strobogrammatic number is a number that looks the same when rotated 180 degrees (looked at upside down). Write a function to count the total strobogrammatic numbers that exist in the range of low . Example 1: Input: low = "50", high = "100" Output: 3 Explanation: 69, 88, and 96 are three strobogrammatic numbers. Solution WebAug 22, 2024 · A strobogrammatic number is a number that looks the same when rotated 180 degrees (looked at upside down). Find all strobogrammatic numbers that are of length = n.
