1417 Reformat The String Kickstart Coding Return the reformatted string or return an empty string if it is impossible to reformat the string. example 1: output: "0a1b2c" explanation: no two adjacent characters have the same type in "0a1b2c". "a0b1c2", "0a1b2c", "0c2a1b" are also valid permutations. example 2: output: "". In depth solution and explanation for leetcode 1417. reformat the string in python, java, c and more. intuitions, example walk through, and complexity analysis. better than official and forum solutions. Return the reformatted string or return an empty string if it is impossible to reformat the string. example 1: input: s = "a0b1c2" output: "0a1b2c" explanation: no two adjacent characters have the same type in "0a1b2c". "a0b1c2", "0a1b2c", "0c2a1b" are also valid permutations. You have to find a permutation of the string where no letter is followed by another letter and no digit is followed by another digit. that is, no two adjacent characters have the same type. return the reformatted string or return an empty string if it is impossible to reformat the string.
