Modify this program so activities take place in methods: Filling array., Printing array, Finding smallest integer in array, finding average of integers in the array. In methods, use array, not nrs$,$ to reference array. Do not remove$/$modify statements in original program; instead, comment them out using $/*.$ Do not use $.$toArray$().$ Program must contain all the original statements.
