( 15662 ) B Lucky Numbers (easy) PROGRAMMING binary search bitmasks brute force #Saitama Destroys Hotel 1400

B"Petya loves lucky numbers. Everybody knows that positive integers are lucky if their decimal representation doesn't contain digits other than 4 and 7. For example, numbers 47, 744, 4 are lucky and 5, 17, 467 are not. Lucky number is super lucky if it's decimal representation contains equal amount of digits 4 and 7. For example, numbers 47, 7744, 474477 are super lucky and 4, 744, 467 are not. One day Petya came across a positive integer n. Help him to find the least super lucky number which is not less than n. The only line contains a positive integer n (1 xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89n xe2 x80 x89 xe2 x89 xa4 xe2 x80 x89109). This number doesn't have leading zeroes. Output the least super lucky number that is more than or equal to n. Please, do not use the %lld specificator to read or write 64-bit integers in C++. It is preferred to use the cin, cout streams or the %I64d specificator."...
