What is the meaning of backtracking?

Retracing your steps

Step-by-step explanation:

Backtracking is a general algorithm for finding all (or some) solutions to some computational problems, notably constraint satisfaction problems, that incrementally builds candidates to the solutions, and abandons a candidate ("backtracks") as soon as it determines that the candidate cannot possibly be completed to a valid solution.[1]

if that is not what you are looking for then the other option would be retracing your steps

Step-by-step explanation:
