Capgemini Exceller has started asking Coding Questions, but it is asked in a special hiring where the package being offered is more than the normal hiring.
- Package offered for this post is 7.5LPA, and since the package being offered is comparatively higher than the normal hiring process, the selection process and test difficulties level are also higher than normal.
- Coding Round is the second major stage of the Capgemini Exceller recruitment process and carries a high weightage in the overall selection. This round tests your problem solving ability, coding logic, and understanding of basic data structures.
Important Details:
- Total Questions: 2
- Difficulty Level: Easy to Medium
- Time Allotted: 45 minutes
- Languages Allowed: C, C++, Java
- Python is NOT allowed in the Exceller drive.

Practice Questions for Capgemini Exceller Coding Round
Question 1:
Problem Statement –
You have write a function that accepts, a string which length is “len”, the string has some “#”, in it you have to move all the hashes to the front of the string and return the whole string back and print it.
char* moveHash(char str[],int n);
Example :
Sample Test Case
Input:
Move#Hash#to#Front
Output:
###MoveHashtoFront
#include<string.h>
#include<stdio.h>
void moveHash(char str[])
{
char str1[100] = {0}, str2[100] = {0};
int i, j = 0, k = 0;
for (i = 0; str[i]; i++)
{
if (str[i] == '#')
str1[j++] = str[i];
else
str2[k++] = str[i];
}
strcat(str1, str2);
printf("%s", str1);
}
int main()
{
char a[100];
scanf("%[^\n]s", a);
moveHash(a);
return 0;
}
#include<bits/stdc++.h>
using namespace std;
char *moveHash(char str[],int n)
{

for(i=0;str[i];i++)
{
if(str[i]=='#')
str1[j++]=str[i];
else
str2[k++]=str[i];
}
strcat(str1,str2);
cout<<str1;
}
int main()
{
char a[100], len;
cin>>a;
len = strlen(a);
moveHash(a, len);
return 0;
}import java.util.*;

str1=str1 + str.charAt(i);

Question 6
Problem Statement –
A function is there which tells how many dealerships there are and the total number of cars in each dealership.
Your job is to calculate how many tyres would be there in each dealership.
Input
