Check symmetric matrix

Square matrix is ​​a matrix of rows and columns of equal. Matrix NxN square matrix called Career N.Ma symmetrical ball is a square matrix with the transposed matrix of it, or AIJ = Aji Recommended Posts: Enter into a square matrix of degree n.

Matrix transposition

If A is a matrix of n x m in size with values ​​aij in row i, column j, the matrix transpose matrix B = AT m x n size with values: bij = aji Example: Threads: For matrix A n x m size. Find the matrix transpose of the matrix A. Input: The first line contains 2

Check array symmetry

Threads: For an array of n integers. Check if the array is mirrored. Plate symmetric arrays when writing in the forward or reverse are identical results. Input: The first line is an integer n. The second line 2 n is an integer array, the number of ways

Check array ascending

Threads: For an array of n integers. Check that the array ascending. Ascending array is larger array that follows the previous number. Input: The first line is an integer n. The second line 2 n is an integer array, of numbers separated by spaces. Output: If

Count the number of

Threads: For an array of n integers. Plate count in how many different numbers and each number appears many times in the array. The number in the array is between 0 come 1000. n <= 100. Input: The first line is an integer n. The second line 2 to be

Three largest

Threads: For an array of n integers. Finding 3 the largest number in the array. Input: The first line is an integer n (n>=3). The second line 2 n is an integer array, of numbers separated by spaces. Output: A line of 3 the largest number in the order of most, second, ba
