一、REVERSE IN ARRAY OPERATIONS 在数组操作中,reverse是一项常用并且直观的功能。数组是一种顺序存储的数据结构,经常需要对数组内元素进行排列顺序的调整。不同编程语言中对数组进行reverse可能的方法包括: 使用内建的reverse函数或方法; 通过数组索引进行手动翻转; 应用双指针技术进行高效翻转。 一、USING BUILT-IN FU...
Approach 6 – Using two pointers function revStr(str) { let arr = new Array(str.length) let left = 0 let right = str.length - 1 while (left <= right) { arr[left] = str[right] arr[right] = str[left] left++ right-- } return arr.join("") }Code language: JavaScript (javascri...
commonly used technique: two pointers: left and right stack LC334/541 Reverse String 334 is a regular reverse char array problme, using only left and right pointers 541 cut the chunk in the size of 2k, and each time we only reverse the first k part. it’s a easy problem. LC151/186...
All the numbers in the input array are in the range of 32-bit integer. Solution 1. Binary Indexed Tree with binary search or coordinate compression, O(N * logN) The keys of a binary indexed tree are all the possible number values. So the high level idea of using a BIT here is that...

Array.Reverse(words); return string.Join(" ", words); } Abhinaba Basu [MSFT] August 2, 2007 Nope the .NET solution won't work as that is not constant space. E.g. your split will create 10 strings if there are 10 words on the stack. Even C++ stl classes support tokenize kind of...
Write a C++ program to reverse a string by swapping its characters in-place using two pointers. Write a C++ program that converts a string to a character array and then reverses it using a for loop. Write a C++ program to reverse a string and then compare it with the original to check...

The interviewees may ask you to write various ways to reverse a string, or they might ask you to reverse a string without using built-in methods, or they might even ask you to reverse a string using recursion. There are occasions where it is simpler to write problems involving regular exp...
