Здравейте колеги, искам да попитам, куъде ми е грешката при кода, имайки предвид, че като го проверявам с ми излизат верни отговори, но в judge ми дава 58/100. Това ми е кода: https://pastebin.com/6JaeQbH5, а ето го и условието: Благодаря предварително :)

 Write a program that reads an array of integers from the console and set of commands and executes them over the array. The commands are as follows:
⦁    add <index> <element> – adds element at the specified index (elements right from this position inclusively are shifted to the right).
⦁    addMany <index> <element 1> <element 2> … <element n> – adds a set of elements at the specified index.
⦁    contains <element> – prints the index of the first occurrence of the specified element (if exists) in the array or -1 if the element is not found.
⦁    remove <index> – removes the element at the specified index.
⦁    shift <positions> – shifts every element of the array the number of positions to the left (with rotation).
⦁    For example, [1, 2, 3, 4, 5] -> shift 2 -> [3, 4, 5, 1, 2]
⦁    sumPairs – sums the elements in the array by pairs (first + second, third + fourth, …).
⦁    For example, [1, 2, 4, 5, 6, 7-, 8] > [3, 9, 13, 8].
⦁    print – stop receiving more commands and print the last state of the array.
