“…Many scholars have contributed, to investigate and studying solutions of FIDEs and FIEs utilizing different numerical and analytical techniques. These techniques include the iterative approximation technique (Abigail, 2019), He's homotopy perturbation method (Sekar & Thirumurugan, 2019), Laplace Adomian Decomposition method (Bushnaq, Ullah, Ullah, & Shah, 2020;Ullah, Ullah, Abdeljawad, Hammouch, & Shah, 2021;Ullah, Ullah, Shah, & Baleanu, 2020), Sumudu decomposition method (Kang, Iqbal, Habib, & Nazeer, 2019), fuzzy differential transform method (Biswas & Roy, 2018), and Kernel Hilbert space method (Gumah, Naser, Al-Smadi, & Al-Omari, 2018), and others (Hooshangian, 2019). The scholars also investigated the existence and the uniqueness of the solution for FIDEs and FIEs (Ali, 2018;Georgieva, 2020;Sindu Devi & Ganesan, 2018;Tunc¸& Tunc¸, 2018).…”
