Given n ranges of the form L and R, the task is to find the maximum occurred integer in all the ranges.If more than one such integer exists, print the smallest one. For example, the following declarations declare variables of the same type:The default value of each integral type is zero, 0. So for example on such a system, intval('1000000000000') will return 2147483647. Does my concept for light speed travel pass the "handwave test"? The two array types are – a linear array that lets you specify the start value, step value, and the number of integers and an array of random integers that have the range start value, range end value, and also the number of output integers.
