Given two sorted integer arrays A and B, merge B into A as one sorted array.
Note:
You may assume that A has enough space (size that is greater or equal to m + n) to hold additional elements from B. The number of elements initialized in A and B are m and n respectively.
public void merge(int A[], int m, int B[], int n) { int pos = m+n-1; m--; n--; while(m>=0 || n>=0) { if(m>=0 && (n<0 || A[m] >= B[n])) { A[pos--] = A[m--]; } else { A[pos--] = B[n--]; } } }
