算法设计（如何打印字符串中每个单词的最后一个字符（）） _字符串

本文概述

C ++
Java
Python3
C#
的PHP

给定一个字符串str, 任务是打印字符串中每个单词的最后一个字符。
例子：

【算法设计（如何打印字符串中每个单词的最后一个字符（））】输入：str ="lsbin in lsbin"
输出：n n n
输入：str ="computer applications"
输出：r s

方法：附加一个空格""在给定字符串的末尾, 以便字符串中的最后一个单词后面也跟一个空格, 就像字符串中的所有其他单词一样。现在开始逐个字符遍历字符串, 并打印每个字符, 后跟一个空格。
下面是上述方法的实现：
C ++

// CPP implementation of the approach #include< bits/stdc++.h> using namespace std; // Function to print the last character // of each word in the given string void printLastChar(string str) {// Now, last word is also followed by a space str = str + " " ; for ( int i = 1; i < str.length(); i++) {// If current character is a space if (str[i] == ' ' )// Then previous character must be // the last character of some word cout < < str[i - 1] < < " " ; } }// Driver code int main() { string str = "lsbin in lsbin" ; printLastChar(str); }// This code is contributed by // Surendra_Gangwar

Java

// Java implementation of the approach class GFG {// Function to print the last character // of each word in the given string static void printLastChar(String str) {// Now, last word is also followed by a space str = str + " " ; for ( int i = 1 ; i < str.length(); i++) {// If current character is a space if (str.charAt(i) == ' ' )// Then previous character must be // the last character of some word System.out.print(str.charAt(i - 1 ) + " " ); } }// Driver code public static void main(String s[]) { String str = "lsbin in lsbin" ; printLastChar(str); } }

Python3

# Function to print the last character # of each word in the given string def printLastChar(string):# Now, last word is also followed by a space string = string + " " for i in range ( len (string)):# If current character is a space if string[i] = = ' ' :# Then previous character must be # the last character of some word print (string[i - 1 ], end = " " )# Driver code string = "lsbin in lsbin" printLastChar(string)# This code is contributed by Shrikant13

// C# implementation of the approach using System; class GFG { // Function to print the last character // of each word in the given string static void printLastChar( string str) { // Now, last word is also followed by a space str = str + " " ; for ( int i = 1; i < str.Length; i++) { // If current character is a space if (str[i] == ' ' ) // Then previous character must be // the last character of some word Console.Write(str[i - 1] + " " ); } } // Driver code public static void Main() { string str = "lsbin in lsbin" ; printLastChar(str); } } // This code is contributed by Ryuga

的PHP

< ?php // PHP implementation of the approach// Function to print the last character // of each word in the given string function printLastChar( $str ) { // Now, last word is also followed by a space $str = $str . " " ; for ( $i = 1; $i < strlen ( $str ); $i ++) { // If current character is a space if (! strcmp ( $str [ $i ], ' ' ))// Then previous character must be // the last character of some word echo ( $str [ $i - 1] . " " ); } }// Driver code $str = "lsbin in lsbin" ; printLastChar( $str ); // This code contributed by PrinciRaj1992 ?>

输出如下：
