C Exercises: Double its value and replace the next number with 0 if current and next value are same and shift all 0's to the end
C Array: Exercise-106 with Solution
Write a C program to convert an array in such a way that it doubles its value. This will replace the next element with 0 if the current and next elements are the same. This program will rearrange the array so that all 0's are moved to the end.
Sample Solution:
C Code:
#include<stdio.h>
void ZerosAtEnd(int arr1[], int n)
{
int ctr = 0;
for (int i = 0; i < n; i++)
if (arr1[i] != 0)
arr1[ctr++] = arr1[i];
while (ctr < n)
arr1[ctr++] = 0;
}
void updateArrayRearrange(int arr1[], int n)
{
if (n == 1)
return;
for (int i = 0; i < n - 1; i++)
{
if ((arr1[i] != 0) && (arr1[i] == arr1[i + 1]))
{
arr1[i] = 2 * arr1[i];
arr1[i + 1] = 0;
i++;
}
}
ZerosAtEnd(arr1, n);
}
void ArrayPrinting(int arr1[], int n)
{
for (int i = 0; i < n; i++)
printf("%d ",arr1[i]);
}
int main()
{
int arr1[] = { 0, 3, 3, 3, 0, 0, 7,7, 0, 9 };
int n = sizeof(arr1) / sizeof(arr1[0]);
printf("The given array is: ");
ArrayPrinting(arr1, n);
updateArrayRearrange(arr1, n);
printf("\nThe new array is: ");
ArrayPrinting(arr1, n);
return 0;
}
Sample Output:
The given array is: 0 3 3 3 0 0 7 7 0 9 The new array is: 6 3 14 9 0 0 0 0 0 0
