The specific algorithm for merging arrays depends on the merging rules.

The general process is as follows:

1 Create a target array large enough to accommodate all elements of the two arrays. If the rule stipulates merging one array into another, then you need to ensure that the target array has space to accommodate both arrays, otherwise an out-of-bounds error will occur.

2 Traverse one of the arrays and assign it to the target array. If one array is merged into another, this step can be omitted;

3 Traverse the other array and insert it into the target array according to the rules.

Under different rules, the merging algorithm will be different. For example, the operation of appending the B array with a length of lb to the end of the A array with a length of la can be written as int?i;

for(i?=?0;?i?

A[la+i]=B[i];

And Arrays A and B of length l are alternately merged into C, which can be written as int?i;

for(i?=?0;?i?

{

C[i*2]?=?A[i];

C[i*2+1]?=?B[i ];

}

No matter what method is used, the essence of merging is to assign each element of A and B to the corresponding position of the target array.
