问题
让我们通过删除表达式中的括号来创建一个简化的表达式。
解决方案
示例 1
Input: A string expression with bracket is as follows:(x+y)+(z+q)The output is as follows:x+y+z+q

示例 2
The input is as follows:(x-y+z)-p+qThe output is as follows:x-y+z-p+q

Algorithm
Refer an algorithm to remove the brackets from a given input.
Step 1: Declare and read the input at runtime.
Step 2: Traverse the string.
Step 3: Copy each element of the input string into new string.
Step 4: If anyone parenthesis is encountered as an element, replace it with empty space.
Example
Following is the C program to remove the brackets from a given input −

Live Demo
–>
#includeint main(){ int i=0,c=0,j=0; char a[100],b[100]; printf("Enter the string :"); scanf("%s",a); while(a[i]!=''){ if((a[i]=='(') && (a[i-1]=='-')){ (c=0)?j=i:j=c; while(a[i]!=')'){ if(a[i+1]=='+') b[j++]='-'; else if(a[i+1]=='-') b[j++]='+'; else if(a[i+1]!=')') b[j++]=a[i+1]; i++; } c=j+1; } else if(a[i]=='(' && a[i-1]=='+'){ (c==0)?j=i:j=c; while(a[i]!=')'){ b[j++]=a[i+1]; i++; } j–; c=j+1; } else if(a[i]==')'){ i++; continue; } else { b[j++]=a[i]; } i++; } b[j]=''; printf("%s",b); return 0;}
