Algo Approach: Use Binary Search to find the location where the element is to be inserted and store in a variable index. Call a function insert(a,index,newVal) where a is the sorted array. Run a for loop until index and copy elements into a new array. newArray[index] = newVal and continue copying elements from the given array into the new Array.
