Webmodification without index check on every iteration: // assign corner value from bottom row to result long result = matrix[len-1][len-1]; // for each row (except last!) add diagonal and next to diagonal values for (int i = 0; i < len-1; i++) result += matrix[i][i] + matrix[i][i+1]; WebNov 1, 2024 · 1. I see you used diagonals in your question. A matrix has two diagonals, the leading diagonal ( \) and the antidiagonal ( / ). Assume your matrix, the 2d array, or 2d arrayList whatever you called, is a i * i matrix, you can calculate in a loop: int leadingDiagonalSum = 0, antiDiagonalSum = 0; int size = arr.size (); for (int i = 0; i < size ...

WebJan 26, 2012 · browse all rows browse all cells if i == j (is in main diagonal): increase one sum if i == n - i + 1 (the other diagonal) increase the second sum. The much nicer and much more effective code (using n, instead of n^2) would be: for ( int i = 0; i < n; i++) { d += a [i] [i]; // main diagonal s += a [i] [n-i-1]; // second diagonal (you'll maybe ...

WebI thought this problem had a trivial solution, couple of for loops and some fancy counters, but apparently it is rather more complicated. So my question is, how would you write (in C) a function traversal of a square matrix in diagonal strips.
