27. Remove Element Given an array and a value, remove all instances of that valuein-placeand return the new length. Do not allocate extra space for another array, you must do this bymodifying the input arrayin-placewith O(1) extra memory. The order of elements can be changed. It doesn...
We define an array is non-decreasing ifarray[i] <= array[i + 1]holds for everyi(1 <= i < n). 题意:给定一个数组,只调整一个元素的条件下,该数组能否变成一个递增的数组, 思路:(参考)用贪心算法,当发现nums[i-1]>nums[i]时,我们希望通过改变一个值,使局部递增。 当没有nums[i-2],或者n...

给你两个按非递减顺序排列的整数数组nums1和nums2,另有两个整数m和n,分别表示nums1和nums2中的元素数目。 请你合并nums2到nums1中,使合并后的数组同样按非递减顺序排列。 注意:最终,合并后数组不应由函数返回,而是存储在数组nums1中。为了应对这种情况,nums1的初始长度为m + n,其中前m个元素表示应合并的元...
我集中去刷easy的所有的array 和string的题目,全刷完后差不多就到了190题。接下来改变策略准备集中刷medium。 说说现在刷题的方法: 1 坚决不看答案,坚决自己写(如果30min没有思路,才看答案,并且标记),从最傻的brute force开始,然后看看能不能自己想出些牺牲space complexity来提高time complexity的方法, 然后再...
