MUST BE WRITTEN IN C PROGRAMMING LANGUAGE CANNOT EDIT TEMPLATE IMAGE IN ANY WAY: Write a program to find and display the largest value in an integer array that is divisible by 3. For example, if the array is: 1 15 2 16 3 17 4 18 5 19 The largest number divisible by 3 is 18 On the other hand, if the array does not contain any values that are divisible by 3, the program writesNo value in the array is divisible by 3As you may see in the examples, the input consists of, firstly the size of the array, followed by the array elements. The answer is preloaded with the code to read in the array. Do not change this code. The Moodle checker expects *exactly* the output as shown. For example: Input Result 6 1 2 3 4 5 6 The largest value divisible by 3 is 6 6 1 -2 4 5 -7 8 No value in the array is divisible by 3
