Can any one tell me the solution of the problem.

Eg. Input: 2 3 9 Output: 3 Explanation: Total sub-array are:- {2}, {3}, {9}, {2, 3}, {3, 9}, {2, 3, 9}

Subarray which violets the property are:- {9} -> {3 * 3}, Since 3 is a repeating prime factor in prime decomposition of 9 {3, 9} -> {3 * 3 * 3}, 3 is a repeating prime factor in prime decomposition of 27 {2, 3, 9} -> {2 * 3 * 3 * 3}, 3 is repeating prime factor in prime decomposition of 54 Hence total subarray remains which satisfies our condition are 3.

Input: 2, 3, 5, 15, 7, 2 Output: 12
