list = {{1, 2}, {2, 3}, {4, 5}, {6, 7}, {3, 1}, {5, 4}, {7, 8}, {8, 9}, {15, 0}, {6, 7}, {9, 7}, {4, 3}, {6, 3}};
list1 = {{a, b}, {d, e}, {t, r}};
I want to replace some elements of list by list1.
Final Result would be look like
finallist = {{1, 2}, {2, 3}, {4, 5}, {6, 7}, {3, 1},{a, b}, {d, e},{8, 9},{15, 0}, {6, 7}, {9, 7}, {4, 3}, {6, 3}};
Please help me, if possible
Module[{r = list}, r[[6 ;; 7]] = list1[[1 ;; 2]]; r]
