then we will get the output string as “htolc”. There exist several methods to perform the string reversal in the C, and they are strev func (), recursion func (), and string reversal using the pointers. We can also verify the palindrome string using the string reversal methods. A pa...
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 we swap the last character and the first ...
We have a string, "Hello World", which we want to reverse: The String to Reverse txt ="Hello World"[::-1] print(txt) Create a slice that starts at the end of the string, and moves backwards. In this particular example, the slice statement[::-1]means start at the end of the st...

Given an input string,reverse the string word by word.For example,Given s="the sky is blue",return"blue is sky the". 比较基础的一个题,拿到这个题,我的第一想法是利用vector来存每一个子串,然后在输出,这是一个比较简单的思路,此外,还有第二个思路,就是对所有的字符反转,然后在针对每一个子串反转...
