Given a short array of integers of length 2 called myShortArray, write pseudocode to determine and output the biggest and second biggest number.

Given an array of integers of length 5 called myLongerArray, write pseudocode to determine and output the biggest number it contains.

Given an array of integers of length 7 called myArray, write pseudocode to output the sum of the two biggest integers it contains. The algorithm should handle both negatives values and repeated values.
