In ΔABC\Delta ABC, ∠ABC=90∘\angle ABC = 90^\circ and BA=BC=2BA = BC = \sqrt{2}. Points P1,P2,…,P2024P_1, P_2, \dots, P_{2024} lie on hypotenuse AC‾\overline{AC} so that AP1=P1P2=P2P3=⋯=P2023P2024=P2024CAP_1= P_1P_2 = P_2P_3 = \dots = P_{2023}P_{2024} = P_{2024}C. What is the length of the vector sum BP1→+BP2→+BP3→+⋯+BP2024→?\overrightarrow{BP_1} + \overrightarrow{BP_2} + \overrightarrow{BP_3} + \dots + \overrightarrow{BP_{2024}}?
