Let \( A \) and \( B \) be two sets each with a finite number of elements. Assume that there is an injective mapping from \( A \) to \( B \) and th at there is an injective mapping from \( B \) to \( A \). Prove that there is a bijective mapping from \( A \) to \( B \).https://bit.ly/YTAI_PWAP https://www.pw.live
