The time complexity of this solution isO(n), wherenis the number of digits in the integer. Adding to aHashSetand checking its size are bothO(1)operations, but we still have to iterate through each digit. 4. Using Stream API Java’sStream APIprovides a concise and modern solution to count...
The code above uses theMath.ceilfunction to round the number since therandomfunction returns the floating-point value. You can multiply the output with10*nto generate anndigit number. The above code’s output will vary each time you run the code. ...
f(3) = f(2) * 8 = 9 * 9 * 8. Because for each number with unique digits of length 2, say ij, we can pick k to form a 3 digit number ijk and there are 8 numbers that are different from i and j for k to choose from. Similarly f(4) = f(3) * 7 = 9 * 9 * 8 *...
Step 1 - Find digit in array A9=$B$1:$E$5 returns {FALSE, FALSE, ... , FALSE} Step 2 - Convert boolean array to row numbers IF(A9=$B$1:$E$5, ROW($B$1:$E$5)-MIN(ROW($B$1:$E$5))+1, "") returns {"", "", ... , ""} Step 3 - Count row numbers FREQUENCY(...
