OOB Accuracy

Compute the out-of-bag accuracy of a bagged ensemble: the fraction of samples whose out-of-bag prediction equals the true label. y_true and y_pred are aligned label arrays.

Implement solve(y_true, y_pred).

Returns. Return a float in $[0,1][0,1]$.

Example 2

Input:

solve([1, 2, 2], [1, 2, 2])
