1. Direct Insert sort (stable sort)Simply put, the sequence is divided into ordered sequence and unordered sequence. Each trip is sorted by inserting the first element of the unordered sequence into an ordered sequence. R[1 I-1] The steps are as

Exception Handling 0 CasesI'm sure you can handle all except 0 o'clock, pass the function and then determine if the divisor is 0, as shown in the code below: double Divide (Doublea,double b) { const double delta = 0.00000000001 ; //
