Title description

Input an incrementally ordered integer array A with n elements, delete the element with subscript i to keep it in continuous order.Note that valid subscripts start at 0.The following two functions are defined to implement delete element operation and array output operation respectively.
void del(int a[], int n, int i); /*Delete the element with index i in the array a*/
void PrintArr(int a[], int n); /*OutputThe first n elements of array a */

Enter

The input is divided into three lines, the first line is an integer n (n<10), the second line is n integers, and the third line is the subscript i of the element to be deleted, i>=0.

Output

Output the array elements after deleting the element with subscript i, and separate the data with spaces.

Sample input Copy

61 3 5 7 9 113

Sample output Copy

1 3 5 9 11

Tips

Please note that when the array has only one element and is deleted, the array is empty, and there should be no output at this time.A common mistake is to output the first element or a carriage return in this case.

#include void del(int a[], int n, int i);void PrintArr(int a[], int n);int main(){int n;int i,j;int a[20];scanf("%d",&n);for(i=0;i

Key analysis of problem solving:

(1) Delete operation

Locate the position to be deleted and move forward in turn (for loop implementation)

Additional: Insert operation: locate the position to be inserted and move backward
