Q. Program to divide a string in 'N' equal parts.Here, our task is to divide the string S into n equal parts. We will print an error message if the string cannot be divisible into n equal parts otherwise all the parts need to be printed as the output of the program. To check whether the string can be divided into N equal parts, we need to divide the length of the string by n and assign the result to variable chars. If the char comes out to be a floating point value, we can't divide the string otherwise run a for loop to traverse the string and divide the string at every chars interval. The algorithm of the program is given below. Algorithm
Complexity:O(n) SolutionPythonstr = "aaaabbbbcccc"; #Stores the length of the string length = len(str); #n determines the variable that divide the string in 'n' equal parts n = 3; temp = 0; chars = int(length/n); #Stores the array of string equalStr = []; #Check whether a string can be divided into n equal parts if(length % n != 0): print("Sorry this string cannot be divided into " + str(n) +" equal parts."); else: for i in range(0, length, chars): #Dividing string in n equal part using substring() part = str[ i : i+chars]; equalStr.append(part); print("Equal parts of given string are"); for i in equalStr: print(i); Output: Equal parts of given string are aaaa bbbb cccc C#include <stdio.h> int main() { char str[] = "aaabbbcccddd"; int i, counter, len = 0, n = 3, temp = 0, chars; len = strlen(str); chars = len/n; char c[chars+1]; //Check whether a string can be divided into n equal parts if(len % n != 0 || n == 0) { printf("Sorry this string cannot be divided into %d equal parts.", n); } else { printf("%d equal parts of given string are\n",n); for(i = 0; i < len; i = i+chars) { counter = 0; //Dividing string in n equal part using substring() while (counter < chars) { c[counter] = str[i + counter]; counter++; } c[counter]='\0'; printf("%s",c); printf("\n"); } } return 0; } Output: 3 equal parts of given string are aaaa bbbb cccc JAVApublic class DivideString { public static void main(String[] args) { String str = "aaaabbbbcccc"; //Stores the length of the string int len = str.length(); //n determines the variable that divide the string in 'n' equal parts int n = 3; int temp = 0, chars = len/n; //Stores the array of string String[] equalStr = new String [n]; //Check whether a string can be divided into n equal parts if(len % n != 0) { System.out.println("Sorry this string cannot be divided into "+ n +" equal parts."); } else { for(int i = 0; i < len; i = i+chars) { //Dividing string in n equal part using substring() String part = str.substring(i, i+chars); equalStr[temp] = part; temp++; } System.out.println(n + " equal parts of given string are "); for(int i = 0; i < equalStr.length; i++) { System.out.println(equalStr[i]); } } } } Output: 3 equal parts of given string are aaaa bbbb cccc C#using System; public class Program { public static void Main() { string str = "aaaabbbbcccc"; //Stores the length of the string int len = str.Length; //n determines the variable that divide the string in 'n' equal parts int n = 3; int temp = 0, chars = len/n; //Stores the array of string String[] equalStr = new String [n]; //Check whether a string can be divided into n equal parts if(len % n != 0) { Console.WriteLine("Sorry this string cannot be divided into "+ n +" equal parts."); } else { for(int i = 0; i < len; i = i+chars) { //Dividing string in n equal part using substring() string part = str.Substring(i, chars); equalStr[temp] = part; temp++; } Console.WriteLine(n + " equal parts of given string are "); for(int i = 0; i < equalStr.Length; i++) { Console.WriteLine(equalStr[i]); } } } } Output: 3 equal parts of given string are aaaa bbbb cccc PHP<!DOCTYPE html> <html> <body> <?php $str = "aaaabbbbcccc"; //Stores the length of the string $len = strlen($str); //n determines the variable that divide the string in 'n' equal parts $n = 3; $temp = 0; $chars = $len/$n; //Stores the array of string $equalStr = array(); //Check whether a string can be divided into n equal parts if($len % $n != 0) { echo "Sorry this string cannot be divided into ", $n ," equal parts."; } else { for($i = 0; $i < $len; $i = $i+$chars) { //Dividing string in n equal part using substring() $part = substr($str, $i, $chars); $equalStr[$temp] = $part; $temp++; } echo $n , " equal parts of given string are <br>"; foreach($equalStr as $v){ echo "$v <br>"; } } ?> </body> </html> Output: 3 equal parts of given string are aaaa bbbb cccc
