1.Determine if a string has all unique characters learn: 为了减少空间利用率,其比较优秀的算法一般都适用位操作 返回值的命名方法,我们需要学习 String 类型作为输入参数,怎么样写比较节省空间与时间,特别是比较长且需要频繁调用的时候 输入为空的时候,不要忘记写不同输入情况下 需要考虑情况的列表 注意String 中...
这三个题目,几乎都要对字符串进行遍历,在遍历中寻求一些逻辑上的计算。 对于第一题,直接遍历判断是否后一个字符和前一个字符是否相同,这样时间复杂度就会很大,相比于把字符的Ascll码直接作为数组的下标,是个不错的选择,这样大大提高了时间效率,不过需要借助一些额外的内存空间。 对于第二题,由于不可以使用额外的缓...
Remember this question is also asked to write a Java program to find repeated characters of a given String, so don't get confused yourself in wording, the algorithm will remain the same.Related Data Structure and Algorithm Interview Questions from Javarevisited Blog Top 30 Array Coding Interview...

In this guide for the day before your coding interview, we have explored some problems and demonstrated the thought process to solve it starting from the brute force solutions. In the process, we have covered all fundamental ideas along with applying Dynamic Programming to String algorithms...
* Question Description: * (Question 30 in <Coding Intervies>) How do you implement a function to check whether there is a * path for a string in a matrix of characters? It moves to left, right, up, and down in a matrix, * and a cell for a step. The path can star...
Question 1.2 of Cracking the Coding Interview:Implement a function void reverse(char* str) in C or C++ which reverses a null-terminated string.This is (implicitly) asking for an in-place reversal of the string. We start by finding the end of the string (or equivalently, its length). Then...
One of the common Java coding interview questions is towrite a program to reverse a String in place in Java, without using additional memory. You cannot use any library classes or methods likeStringBuilderto solve this problem. This restriction is placed becauseStringBuilderandStringBufferclass define...
This is the best type of interview question that tests candidates’ ability to think programmatically and coding fluency. To perform well, we have to be familiar with the basic operations of arrays/strings, matrix and its row/column structures, and Python syntax. In two similar blog posts, I...
