Java program to remove all 10s from the array. Write a program to read an integer array and remove all 10s from the array, shift the other elements towards left and fill the trailing empty positions by 0 so that the modified array is of the same length of the given array.
The return type (Integer array) should return the final array.
Input and Output Format:
Input consists of n+1 integers, where n corresponds to size of the array followed by n elements of the array.
Output consists of an integer array (the final array).
Refer sample output for formatting specifications.
Sample Input :
5
