please I would like help completing this code:

Add PLL.c, PLL.h, UART.c, UART.h, tm4c123gh6pm.h in your program.

Copy the content of the following files into your main program.

// U0Rx (VCP receive) connected to PA0

// U0Tx (VCP transmit) connected to PA1

#include "PLL.h"

#include "UART.h"

// **************Average3 Function*****************

// Write a function that calculates the average of three numbers

// Inputs: x,y,z 32-bit unsigned numbers

// Output: average of x,y,z

uint32_t Average3(uint32_t x, uint32_t y, uint32_t z){

// write code here

return 0; // replace this line with solution

}

// **************Max3 Function*****************

// Write a function that calculates the maximum of three numbers

// Inputs: x,y,z 32-bit unsigned numbers

// Output: maximum of x,y,z

uint32_t Max3(uint32_t x, uint32_t y, uint32_t z){

// write code here

return 0; // replace this line with solution

}

uint32_t Data[10]={100,200,500,300,400,700,300,0,600,400};

// **************Max10*****************

// Write a function that calculates the maximum of 10 numbers

// Inputs: 10 numbers in Data array

// Output: maximum of these 10 numbers

uint32_t Max10(void){

// write code here

return 0; // replace this line with solution

}

uint8_t Data2[4]={1,2,3,4}; // change it to 4,3,2,1

// **************Reverse4*****************

// Write a function that reverses the order of numbers in a 4-element array

// Inputs: 4 numbers in Data2 array

// Output: modify the array reversing the order

void Reverse4(void){

// write code here

}

uint8_t Data3[11]={0,1,2,3,4,5,6,7,8,9,10}; // change it to 10,9,8,7,6,5,4,3,2,1,0

// **************Reverse11*****************

// Write a function that reverses the order of numbers in an 11-element array

// Inputs: 11 numbers in Data3 array

// Output: modify the array reversing the order

void Reverse11(void){

// write code here

}

//testing code
