17. BINARY SEARCH on 2d arrrays

Image
 1.)   ROW WITH MAX 1s- given each row is sorted. BRUTE - simple 2 loops OPTIMAL - binary search lagalo to find index of 1st occurence of 1 in a row -------------------------------------------------------------------------------------------------------------- 2.) Search in 2d Matrix-(sorted rows consecutive) BRUTE - use 2 loops BETTER - check for only that row jisme target is between a[i][0] and a[i][c-1]  OPTIMAL - 2d array ko hypothetically 1d me karke binary search lagalo --------------------------------------------------------------------------------------------------------------- 3.) Search in matrix(sorted row and col but not consecutive) BETTER- use binary search for every row OPTIMAL -(time: N+M) --------------------------------------------------------------------------------------------------------------- 4.) Peak elements in matrix- BRUTE- 1.) we can do linear search and for each element compare with its 4 neighbours 2.) Or, we can find max element in matrix BET...
