It is seen that the number, 125874 and its double 251748, contain exactly the same digits, but in a different order. Write a java program to find and print the smallest positive integer, x such that 2x, 3x, 4x, 5x and 6x contain the same digits.

Machan array anan manan use karanna baaa.. Only loops mchn.. for, while, do while walin thmi gema gahanna oona
