For example, String[][][] data = new String[3][4][2]; Importantly, the output array … We are going to use a hashmap let us consider an example for given an array of pairs, Find all Symmetric Pairs in iteval(ez_write_tag([[300,250],'tutorialcup_com-medrectangle-4','ezslot_8',621,'0','0'])); We will be storing the array’s pairs value into firstValue and secondValue and then we will be checking it. A symmetric matrix is a square matrix that is equal to its transpose. ... As we can see, the code iterates through half of the array, changing the elements in symmetric positions. - Python. Symmetric matrix program in java. The idea is to consider every pair and insert the pair into a set. pairs that are mirror of each other. For complete explanation, refer Two Dimensional Array in Java. then j initialized to 0. while loop iterates until the condition j
