WebMay 27, 2024 · Use Recurrence to Generate All Possible Combinations in Java. First, we create an empty array that will store the outputs. The idea is to fix elements one by one and then use recurrence. Finally, when the number of elements in the initial array becomes equal to the size of combinations, then we print the initial array. Web2) Permutation: It refers to the number of ways a particular set can be arranged, where order of the arrangement matters. A combination lock can be called a permutation lock. For example: i) Let we have three letters a, b, and c and we have to arrange two letters at a time.
