data has duplicated values(9) name of columns must be changed to understand column(Bare Nuclei )should be change to int also, column (Bare Nuclei)has wrong value is ? should change

model

we used K-Nearst Neighbours algorithm.K-Nearest Neighbors is a supervised learning algorithm. Where the data is 'trained' with data points corresponding to their classification. To predict the class of a given data point, it takes into account the classes of the 'K' nearest data points and chooses the class in which the majority of the 'K' nearest data points belong to as the predicted class.The best accuracy was with 0.9857142857142858 with k= 1.
