13026 - Third Largest Number   

Status  |  Limits Submit

Description

Implement the C function find_third_largest() that finds the 3rd largest number of four numbers and store the result in the fifth argument. The prototype for the function is as follows:


void find_third_largest(const int*num1, const int*num2, const int*num3, const int*num4, int* ptr_result);
 
Assume that the main function that calls this function looks like this:
 
int main() {    
    int num1, num2, num3, num4, third_largest;   
    scanf("%d %d %d %d", &num1, &num2, &num3, &num4);   
    find_third_largest(&num1, &num2, &num3, &num4, &third_largest);   
    printf("The 3rd largest element is %d\n", third_largest);    
    return 0;
}
 
You need to implement the function and submit it as follow:
 
void find_third_largest(const int* num1, const int* num2, const int* num3, const int* num4, int* ptr_result){
...
...
}

Input

A list of four integers.

Output

"The 3rd largest element is X\n"

13027 - Matrix Multiplication   

Status  |  Limits Submit

Description

If A is an m × n matrix and B is an n × p matrix,

the matrix product C = AB (denoted without multiplication signs or dots) is defined to be the m × p matrix

 

such that

Compute C = A × B, where A, B and C are matrices of size n × m, m × p, and n × p, respectivily.

 

Implement the matrix multiplication function matrix_mult(). The code is attached to the problem below.

 

All you need to submit are：

 

void matrix_mult(int *const *const matrixA, int rows_A, int cols_A, int *const *const matrixB, int rows_B, int cols_B, int *const *const matrixC)

{   

/* TODO: Your Code here */

}

Reference code (13027.c) for this question is at the very bottom of this page under Partial Judge Code heading.

Input

n, m, where n is row and m is column.

Followed by matrix A elements.

 

m, p, where m is row and p is column.

Followed by matrix B elements.

Output

Matrix C elements.

13031 - The Length Of The Longest Palindromic   

Status  |  Limits Submit

Description

 

  • A palindrome is a word like “deed” or “level”, which remains the same when you spell it backward.

  • We assume that the input string terminates with a period '.' and the length of input string is less than 100.

  • Implementing the function int maxlength_palindrom(char input[], int length)​ that finds the length of the longest palindromic substring of the input string.

 

All you need to submit are:

 

int maxlength_palindrom(char input[], int length)

{

/* TODO: Your Code here */

} 

Reference code for this question is at the very bottom of this page under Partial Judge Code heading.

Input

String of characters that terminates with a period '.'

Output
