This function throws an exception if either element are swapped or an operation on iterator throws an exception. Given a word, find lexicographically greater permutation of it. comp: A user-defined binary predicate function that accepts two arguments and returns true if the two arguments are in order, otherwise returns false. Attention reader! Suppose we have a finite sequence of numbers like (0, 3, 3, 5, 8), and want to generate all its permutations. JavaTpoint offers college campus training on Core Java, Advance Java, .Net, Android, Hadoop, PHP, Web Technology and Python. “permutation gfg” Code Answer . whatever by Homeless Hornet on May 01 2020 Donate .
