Given an array of positive integers nums and a positive integer target, return the minimal length of a contiguous subarray [numsl, numsl+1, ..., numsr-1, numsr] of which the sum is greater than or equal to target. If there is no such subarray, return 0 instead. Example 1: Input: target = 7, nums = [2,3,1,2,4,3] Output: 2 Explanation: The subarray [4,3] has the minimal length under the problem co..

Reconsider the Space Limitation Java public int removeElement(int[] nums, int val) { int k = 0; for (int i = 0; i < nums.length; ++i) { if (nums[i] != val) { nums[k] = nums[i]; k++; } } return k; } Go func removeElement(nums []int, val int) { k := 0; for i:=0; i < nums.length; i++{ if nums[i] != val{ nums[k] = nums[i] k++ } } return k }

Given a 1-indexed array of integers numbers that is already sorted in non-decreasing order, find two numbers such that they add up to a specific target number. Let these two numbers be numbers[index1] and numbers[index2] where 1

Introduction Reflection and structs Reflection and struct tags Reflections and interfaces In the previous, we took a big step in understanding how reflection works in the Go language. Now we will dive deeper into the topic by covering how to use reflection with structs and interfaces. In this lecture, we will start by explaining how reflection needs structs And then we&#39;ll explore struct tags..

Write a function that reverses a string. The input string is given as an array of characters s. You must do this by modifying the input array in-place with O(1) extra memory. Example 1: Input: s = ["h","e","l","l","o"] Output: ["o","l","l","e","h"] Example 2: Input: s = ["H","a","n","n","a","h"] Output: ["h","a","n","n","a","H"] Constraints: 1

Reverse the elements in an array. Java public static void reverse(int[] v, int N) { int i = 0; int j = N - 1; while (i < j) { swap(v, i, j); // this is a self-defined function i++; j--; } } GO func reverse(v []int, N int) { var i int = 0 var j = N - 1 for i < j { swap(v, i, j) // this is a self-defined function i++ j-- } }

Write a function to find the longest common prefix string amongst an array of strings. If there is no common prefix, return an empty string "". Example 1: Input: strs = ["flower","flow","flight"] Output: "fl" Example 2: Input: strs = ["dog","racecar","car"] Output: "" Explanation: There is no common prefix among the input strings. Constraints: 1

Implement strStr(). Given two strings needle and haystack, return the index of the first occurrence of needle in haystack, or -1 if needle is not part of haystack. Clarification: What should we return when needle is an empty string? This is a great question to ask during an interview. For the purpose of this problem, we will return 0 when needle is an empty string. This is consistent to C's strs..
