/* Author: LukArToDo Created: 19.april 2018 Bugs: unknown Description: The code finds gravity of randomly numbers [0-9] according to the next rules: (<<) = Mass to left is greater. (>>) = Mass to Right is greater. (><) = Mass is equal both sides. (0) = Blackhole all surrounding mass gravitates towards this. 🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸 ENTER A TWO POSITIVE INTEGERS SEPARATED BY SPACE (first number=rows, second number=columns) ✔️press submit 🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸🔸 */ fun main(LukArToDo: Array) { try { // take input from user (number of rows and columns separated by space) val(row,col)=readLine()!!.split(' ').map(String::toInt) // create array[row][col] which contains randomly numbers in range [0-9] val arr=Array(row, { IntArray(col, { (Math.random()*10).toInt() }) }) // passing through the array (each element of array) for(i in 0 until row){ var(s1,s2)=arrayOf(" ", " ") for(j in 0 until col){ // checking the mass and gravity between neighbors in rows if(i>" else if(arr[i][j]==0 &&arr[i][j+1]!=0||arr[i][j]>arr[i][j+1]) "<<" else "><")) // printout of number in last column if(j==col-1) print(" ${arr[i][j]}") } // printout the gravity between neighbors in rows print("\n$s1\n$s2\n") } }catch (e:Exception){print("Wrong input.
