Amr doesn't like large arrays so he intends to make it smaller.\n\n Amr doesn't care about anything in the array except the beauty of it. The beauty of the array is defined to be the maximum number of times that some number occurs in this array. He wants to choose the smallest subsegment of this array such that the beauty of it will be the same as the original array.\n\n Help Amr by choosing the smallest subsegment possible.\n\n Input\n The first line contains one number n (1\u2009\u2264\u2009n\u2009\u2264\u2009105), the size of the array.\n\n The second line contains n integers ai (1\u2009\u2264\u2009ai\u2009\u2264\u2009106), representing elements of the array.\n\n Output\n Output two integers l,\u2009r (1\u2009\u2264\u2009l\u2009\u2264\u2009r\u2009\u2264\u2009n), the beginning and the end of the subsegment chosen respectively.\n\n If there are several possible answers you may output any of them.\n\n Sample test(s)\n input\n 5\n 1 1 2 2 1\n output\n 1 5\n input\n 5\n 1 2 2 3 1\n output\n 2 3\n input\n 6\n 1 2 2 1 1 2\n output\n 1 5\n Note\n A subsegment B of an array A from l to r is an array of size r\u2009-\u2009l\u2009+\u20091 where Bi\u2009=\u2009Al\u2009+\u2009i\u2009-\u20091 for all 1\u2009\u2264\u2009i\u2009\u2264\u2009r\u2009-\u2009l\u2009+\u20091\n*/\n\n$count = fgets(STDIN);\n$elementsStr = fgets(STDIN);\n\n$elements = explode(' ', $elementsStr);\n\n$m = array_fill(0, 100005, 0); // The array to mark the occurrence times of each element\n$L = array_fill(0, 100005, 0); // The array to mark the first time element appearance\n\n$maxi = 0;\n$mini = 0;\n$ch = -1; // The start\n\nfor ($i = 0; $i < $count; $i++)\n{\n $x = $elements[$i];\n\n if (empty($m[$x]))\n {\n $L[$x] = $i;\n $m[$x] = 1;\n }\n else\n {\n $m[$x]++;\n }\n\n // The occurrence times is bigger\n if ($m[$x] > $maxi)\n {\n $maxi = $m[$x]; // The max occurrence times\n $mini = $i - $L[$x] + 1; // The subsegment length (We should count the start and end both)\n $ch = $L[$x] + 1; // Output is to start from 1 as beginning the input array\n }\n // The length is shorter, we change the start and min length\n else if ($m[$x] == $maxi && $i - $L[$x] + 1 < $mini)\n {\n $mini = $i - $L[$x] + 1;\n $ch = $L[$x] + 1;\n }\n}\n\necho $ch . \" \" .
