Given two integer arrays arr1 and arr2, return the minimum number of operations (possibly zero) needed to make arr1 strictly increasing.
In one operation, you can choose two indices 0 <= i < arr1.length and 0 <= j < arr2.length and do the assignment arr1[i] = arr2[j].
If there is no way to make arr1 strictly increasing, return -1.
\n
Example 1:
\n\n\nInput: arr1 = [1,5,3,6,7], arr2 = [1,3,2,4]\nOutput: 1\nExplanation: Replace\n\n5with2, thenarr1 = [1, 2, 3, 6, 7].\n
Example 2:
\n\n\nInput: arr1 = [1,5,3,6,7], arr2 = [4,3,1]\nOutput: 2\nExplanation: Replace\n\n5with3and then replace3with4.arr1 = [1, 3, 4, 6, 7].\n
Example 3:
\n\n\nInput: arr1 = [1,5,3,6,7], arr2 = [1,6,3,3]\nOutput: -1\nExplanation: You can't make arr1 strictly increasing.\n\n\n
Constraints:
\n\n1 <= arr1.length, arr2.length <= 20000 <= arr1[i], arr2[i] <= 10^9\n", "translatedTitle": null, "translatedContent": null, "isPaidOnly": false, "difficulty": "Hard", "likes": 2163, "dislikes": 47, "isLiked": null, "similarQuestions": "[{\"title\": \"Make Array Non-decreasing or Non-increasing\", \"titleSlug\": \"make-array-non-decreasing-or-non-increasing\", \"difficulty\": \"Hard\", \"translatedTitle\": null}]", "exampleTestcases": "[1,5,3,6,7]\n[1,3,2,4]\n[1,5,3,6,7]\n[4,3,1]\n[1,5,3,6,7]\n[1,6,3,3]", "categoryTitle": "Algorithms", "contributors": [], "topicTags": [ { "name": "Array", "slug": "array", "translatedName": null, "__typename": "TopicTagNode" }, { "name": "Binary Search", "slug": "binary-search", "translatedName": null, "__typename": "TopicTagNode" }, { "name": "Dynamic Programming", "slug": "dynamic-programming", "translatedName": null, "__typename": "TopicTagNode" }, { "name": "Sorting", "slug": "sorting", "translatedName": null, "__typename": "TopicTagNode" } ], "companyTagStats": null, "codeSnippets": [ { "lang": "C++", "langSlug": "cpp", "code": "class Solution {\npublic:\n int makeArrayIncreasing(vector
