Which is the maximum size sub-matrix with all 1s?
Maximum size sub-matrix is: 1 1 1 1 1 1 1 1 1 Time Complexity: O(m*n) where m is number of rows and n is number of columns in the given matrix. Auxiliary Space: O(m*n) where m is number of rows and n is number of columns in the given matrix. Algorithmic Paradigm: Dynamic Programming
How to set all 1s in a boolean matrix?
1) Scan the first row and set a variable rowFlag to indicate whether we need to set all 1s in first row or not. 2) Scan the first column and set a variable colFlag to indicate whether we need to set all 1s in first column or not.
How are the elements of a matrix printed?
Approach: The problem can be solved by dividing the matrix into loops or squares or boundaries. It can be seen that the elements of the outer loop are printed first in a clockwise manner then the elements of the inner loop is printed.
How to print a matrix in a spiral form?
The first for loop represents the movement from left to right, whereas the second crawl represents the movement from top to bottom, the third represents the movement from the right to left, and the fourth represents the movement from bottom to up. Run a loop until all the squares of loops are printed.
How to find the maximum size of a binary matrix?
Given a binary matrix, find the maximum size rectangle binary-sub-matrix with all 1’s. Recommended: Please solve it on “ PRACTICE ” first, before moving on to the solution.
How to count sets in a binary matrix?
Given a n × m binary matrix, count the number of sets where a set can be formed one or more same values in a row or column. Input: 1 0 1 0 1 0 Output: 8 Explanation: There are six one-element sets (three 1s and three 0s).
How to find the row number of a matrix?
Efficient Approach: Start with the top left corner with index (1, n) and try to go left until you reach the last 1 in that row (jth column), now if we traverse left to that row, we will find 0, so switch to the row just below, with the same column.
