(10 points; 2 points each part) Select a signature for each method described below. Do not write the methods! 3. a) The method finds the smallest value in an array of doubles. b) The method finds whether or not a given value occurs in an array of integers. c) The method returns a new array of doubles that contains the same values in a given array, with the array values repeated twice. Ex: If the array contains (1.0, 2.0, 3.0l, the resulting array would be (1.0, 2.0, 3.0, 1.0, 2.0, 3.0) d) The method puts a range of data in an array of doubles in reverse sorted order. The range is indicated by the given low (inclusive) and high (exclusive) indices. If the array contained (1.0, 2.0, 3.0, 4.0, 5.0 and the indices were between 3 and 5, the array would contain [1.0, 2.0, 4.0, 3.0, 5.0) after the method was executed. e) The method creates an array of double of a given size with randomly generated elements. Each array element should be between 0 and a given high value (that is positive)
