Find the first repeating element in an array of integers
WebYour task is to find the missing number (M) and the repeating number (R). For example: Consider an array of size six. The elements of the array are { 6, 4, 3, 5, 5, 1 }. The array should contain elements from one to six. Here, 2 is not present and 5 is occurring twice. Thus, 2 is the missing number (M) and 5 is the repeating number (R).
