Lion king from the jungles of Hakuna Matata likes random numbers. Let F4(X) be the number of digits 4 in the decimal representation of X, and F7(X) be the number of digits 7 in the decimal representation of X. The Lion king wants to know the largest product F4(X) · F7(X), where L< X s R. In other words, he wants to know the value max{F4(X) · F7(X) : L < X < R}. Create a C++ code for the printing the output of the test case.
