( 348 ) | G | The Sum of Good Numbers | PROGRAMMING | hashing probabilities |
B"Let's call a positive integer good if there is no digit 0 in its decimal representation. For an array of a good numbers a , one found out that the sum of some two neighboring elements is equal to x (i.e. x = a_i + a_{i + 1} for some i ). x had turned out to be a good number as well. Then the elements of the array a were written out one after another without separators into one string s . For example, if a = [12, 5, 6, 133] , then s = 1256133 . You are given a string s and a number x . Your task is to determine the positions in the string that correspond to the adjacent elements of the array that have sum x . If there are several possible answers, you can print any of them. The first line contains the string s ( 2 <= |s| <= 5 cdot 10^5 ). The second line contains an integer x ( 2 <= x < 10^{200000} ). An additional constraint on the input: the answer always exists, i.e you can always select two adjacent substrings of the string s so that if you convert these substrings to integers, their sum is equal to x . In the first line, print two integers l_1 , r_1 , meaning that the first term of the sum ( a_i ) is in the string s from position l_1 to position r_1 . In the second line, print two integers l_2 , r_2 , meaning that the second term of the sum ( a_{i + 1} ) is in the string s from position l_2 to position r_2 . In the first example s[1;2] = 12 and s[3;3] = 5 , 12+5=17 . In the second example s[2;3] = 54 and s[4;6] = 471 , 54+471=525 . In the third example s[1;1] = 2 and s[2;2] = 3 , 2+3=5 . In the fourth example s[2;7] = 218633 and s[8;13] = 757639 , 218633+757639=976272 . "... |
