double mean(int nums[], int len)
Description: This function calculates the arithmetic mean of the array nums.
 Method Call return value/output mean({2,3,4} ,3 ) 3 mean({3 , 4 } 2 } 3.5
int largest(int nums[], int len)
Description: This function returns the largest value of the array.
 Method Call return value/output largest({2,3,4} , 3) 4 largest({ 5, 12, 3, 7, 4 }, 5 } 12 largest( { -2, -3, -4} , 3) -2
int[] doubleAnArr(int nums[], int len)
Description: This function returns an array that has two copies of the original array..
 Method Call return value/output doubleAnArr({2,3,4} ) {2 , 3, 4 , 2 , 3 , 4 } doubleAnArr({,6, 11} } { 6 , 11 , 6 , 11}
void printSum(int num1[], int num2[], int length)
Description: Assume that each element in num1 and num2 are digits in a number. Also assume that both eleements have length digits. Store the resulting sum into a new array that you will then print out. If the result of the addition is more than length long, then simply output the message "Addition Overflow" and nothing else . (We can't return the .
 Method Call return value/output printSum( {2,3,4} , {2,2,9} ) { 4, 6 , 3} printSum( {9,3,4} , {2,2,9} ) "Additional Overflow"
