WebbOK, I changed the variable name, though it's a bit beside the point for this. To use a generator expression instead change [] to ().I will leave the list form in the answer so it is clearer to anyone not familiar with it (like anyone with the same question as OP). WebbNow we run another loop from j = i to n - 1 to find the first missing positive number. Outside the loop, we also declare a variable missingPositive to track to the first missing positive. The missingPositive will be initialized with the smallest positive number i.e. 1 at the start. We start comparing the missingPositive with X[j].
