Program to Remove All the White Spaces from a String
Program to Remove All the White Spaces from a String on fibonacci, factorial, prime, armstrong, swap, reverse, search, sort, stack, queue, array, linkedlist, tree, graph etc.
Q. Program to remove all the white spaces from a string.
In this program, our task is to remove all the white-spaces from the string. For this purpose, we need to traverse the string and check if any character of the string is matched with a white-space character or not. If so, Use any built-in method like replace() with a blank. In C, we do not have any built-in method to replace. Therefore, We need to run the for loop to traverse the string and see if there is any white-space character or not. If so, then start the inner loop (j) from ith character to len and keep replacing each element with its next adjacent element. Decrease the length of the string by 1 on the termination of this loop. Repeat this process until all the white-spaces of the string are removed. Algorithm
SolutionPython
str1 = "Remove white spaces";
#Using in-built function in python
#Here, we are replacing space character with blank
str1 = str1.replace(" ","");
print("String after removing all the white spaces : " + str1);
Output: String after removing all the white spaces : Removewhitespaces C
#include <stdio.h>
int main()
{
int i, len = 0,j;
char str[] = "Remove white spaces";
//Calculating length of the array
len = sizeof(str)/sizeof(str[0]);
//Checks for space character in array if its there then ignores it and swap str[i] to str[i+1];
for(i = 0; i < len; i++){
if(str[i] == ' '){
for(j=i;j<len;j++)
{
str[j]=str[j+1];
}
len--;
}
}
printf("String after removing all the white spaces : %s", str);
return 0;
}
Output: String after removing all the white spaces : Removewhitespaces JAVA
public class removeWhiteSpace {
public static void main(String[] args) {
String str1="Remove white spaces";
//Removes the white spaces using regex
str1 = str1.replaceAll("\\s+", "");
System.out.println("String after removing all the white spaces : " + str1);
}
}
Output: String after removing all the white spaces : Removewhitespaces C#
using System;
public class Program
{
public static void Main()
{
string str1="Remove white spaces";
//Removes the white spaces using regex
str1 = str1.Replace(" ",String.Empty);
Console.WriteLine("String after removing all the white spaces : " + str1);
}
}
Output: String after removing all the white spaces : Removewhitespaces PHP
